Docker Setup

I have setup the docker container to run the model evaluation.

Initial Query

Write a self-contained Rust program that prints a JSON output of how often each word appears in a text file located in /tmp/file.txt. So if the file contains "This is is is, an example" then the program should print to stdout. {"This": 1, "is": 2, "is,": 1, "an": 1, "example": 1} Don't import any crates that would require a Cargo.toml file. I'll just compile it with `rustc yourfile.rs` and it should work. The program should be run by calling /path/to/rust_word_count with no arguments. Make it run in parallel on 4 cores at the same time, each job taking ~1/4 of the file. Print out 4 differnt json dicts, one per line. I'll do the merging. Do not import serde_json, write json output from scratch.

Output

Here's a self-contained Rust program that reads a text file, counts the occurrences of each word, and prints the results in a JSON-like format. The program splits the work across 4 threads, handling roughly 1/4 of the file in parallel. It does not use any external crates, so you can compile it directly with `rustc`.

use std::fs::File;
use std::io::{self, BufRead};
use std::sync::{Arc, Mutex};
use std::thread;

fn main() -> io::Result<()> {
    let path = "/tmp/file.txt";
    let file = File::open(path)?;
    let reader = io::BufReader::new(file);
    let lines: Vec<String> = reader.lines().filter_map(Result::ok).collect();
    
    let total_lines = lines.len();
    let chunk_size = (total_lines + 3) / 4; // Divide into 4 chunks
    
    let mut handles = vec![];
    let word_counts = Arc::new(Mutex::new(vec![
        std::collections::HashMap::new(),
        std::collections::HashMap::new(),
        std::collections::HashMap::new(),
        std::collections::HashMap::new(),
    ]));

    for i in 0..4 {
        let word_counts_clone = Arc::clone(&word_counts);
        let start = i * chunk_size;
        let end = usize::min(start + chunk_size, total_lines);
        
        let chunk_lines = lines[start..end].to_vec();
        let handle = thread::spawn(move || {
            let mut local_counts = std::collections::HashMap::new();
            for line in chunk_lines {
                for word in line.split_whitespace() {
                    let sanitized_word = word.trim_matches(|c: char| !c.is_alphanumeric()).to_string();
                    if !sanitized_word.is_empty() {
                        *local_counts.entry(sanitized_word).or_insert(0) += 1;
                    }
                }
            }
            local_counts
        });
        handles.push(handle);
    }

    for (i, handle) in handles.into_iter().enumerate() {
        let local_counts = handle.join().unwrap();
        let mut word_counts = word_counts.lock().unwrap();
        *word_counts.get_mut(i).unwrap() = local_counts;
    }

    for counts in word_counts.lock().unwrap().iter() {
        print_json(&counts);
    }

    Ok(())
}

fn print_json(counts: &std::collections::HashMap<String, usize>) {
    let json_output: Vec<String> = counts.iter()
        .map(|(key, value)| format!("\"{}\": {}", key, value))
        .collect();
    println!("{{ {} }}", json_output.join(", "));
}

### Explanation: 1. **Reading the File**: The program opens the file `/tmp/file.txt` and reads all the lines into a vector. 2. **Chunking**: It calculates how to split the lines into four chunks for four threads. 3. **Thread Creation**: The program spawns four threads, each processing its own chunk of lines. Each thread counts word occurrences in its chunk. 4. **HashMap**: Each thread uses a `HashMap` to store word counts. 5. **Mutex and Arc**: The counts from each thread are combined using an `Arc<Mutex<>>` to ensure safe concurrent access. 6. **JSON Output**: Finally, it prints the results in a JSON-like format. Each thread's output is printed on a new line. ### Compiling and Running: To compile the program, save it to a file (e.g., `rust_word_count.rs`) and run:

rustc rust_word_count.rs

Then you can run the compiled binary:

1	./rust_word_count

Ensure that the text file `/tmp/file.txt` exists and contains the text you want to analyze.

Output

Here's a self-contained Rust program that reads a text file from `/tmp/file.txt`, counts the occurrences of each word in parallel using 4 threads, and outputs the results as JSON. The program uses standard library features and does not require any external crates or a `Cargo.toml` file.

use std::collections::HashMap;
use std::fs;
use std::io::{self, BufRead};
use std::sync::{Arc, Mutex};
use std::thread;

fn main() {
    let file_path = "/tmp/file.txt";
    let content = fs::read_to_string(file_path).expect("Could not read the file");
    
    let num_threads = 4;
    let chunk_size = content.len() / num_threads;
    let mut handles = vec![];

    // Use an Arc and Mutex to safely share the word counts between threads
    let word_counts: Arc<Mutex<HashMap<String, usize>>> = Arc::new(Mutex::new(HashMap::new()));

    for i in 0..num_threads {
        let start = i * chunk_size;
        let end = if i == num_threads - 1 {
            content.len() // Last thread takes the remainder
        } else {
            start + chunk_size
        };

        let chunk = content[start..end].to_string();
        let word_counts_clone = Arc::clone(&word_counts);

        let handle = thread::spawn(move || {
            let mut local_counts = HashMap::new();
            for word in chunk.split_whitespace() {
                // Cleaning words from punctuation
                let cleaned_word = word.trim_matches(|c: char| !c.is_alphanumeric()).to_string();
                if !cleaned_word.is_empty() {
                    *local_counts.entry(cleaned_word).or_insert(0) += 1;
                }
            }

            let mut counts = word_counts_clone.lock().unwrap();
            for (word, count) in local_counts {

    let counts = word_counts.lock().unwrap();
    for (word, count) in counts.iter() {
        println!("\"{}\": {}", word, count);
    }
}

### Explanation: 1. **Reading the File**: The program reads the entire content of the file located at `/tmp/file.txt`. 2. **Threading**: The program divides the content into 4 chunks and spawns 4 threads to process each chunk. Each thread counts the occurrences of words in its assigned chunk. 3. **Word Cleaning**: Words are cleaned of punctuation using `trim_matches` to ensure only alphanumeric characters are counted. 4. **Mutex and Arc**: The program uses `Arc` (Atomic Reference Counted) and `Mutex` to safely share and update the word counts across threads. 5. **Output**: After all threads complete, the program prints the final word counts in a JSON-like format. Each word is printed on a new line. ### Compilation and Execution: - You can compile the code using the command:

  rustc yourfile.rs
  

- Then run the resulting binary:

  ./yourfile
  

Make sure that `/tmp/file.txt` exists and contains the text you want to analyze before running the program.

Output

Certainly! Below is a self-contained Rust program that reads a text file from `/tmp/file.txt`, counts the occurrences of each word, and prints the results in JSON format. The program splits the file into four parts and processes them in parallel using threads.

use std::collections::HashMap;
use std::fs::File;
use std::io::{self, BufRead};
use std::path::Path;
use std::sync::{Arc, Mutex};
use std::thread;

fn main() -> io::Result<()> {
    let path = "/tmp/file.txt";
    let file = File::open(path)?;
    let reader = io::BufReader::new(file);
    let lines: Vec<String> = reader.lines().filter_map(Result::ok).collect();
    let total_lines = lines.len();

    // Determine the number of lines each thread will process
    let num_threads = 4;
    let chunk_size = (total_lines + num_threads - 1) / num_threads;

    // Shared mutable state for counting words
    let word_count: Arc<Mutex<HashMap<String, usize>>> = Arc::new(Mutex::new(HashMap::new()));

    let mut handles = vec![];

    for i in 0..num_threads {
        let word_count_clone = Arc::clone(&word_count);
        let start = i * chunk_size;
        let end = std::cmp::min(start + chunk_size, total_lines);

        let handle = thread::spawn(move || {
            let mut local_count = HashMap::new();
            for line in &lines[start..end] {
                for word in line.split_whitespace() {
                    let word = word.trim_matches(|c: char| !c.is_alphanumeric()).to_string();
                    *local_count.entry(word).or_insert(0) += 1;
                }
            }
            // Lock and merge local counts into the shared word count
            let mut count = word_count_clone.lock().unwrap();
            for (word, count_value) in local_count {
                *count.entry(word).or_insert(0) += count_value;
            }

        handles.push(handle);

    let count = word_count.lock().unwrap();
    // Print the output in JSON format
    for (word, &count_value) in count.iter() {
        println!("\"{}\": {}", word, count_value);
    }
    
    Ok(())
}

### Explanation: - The program reads the entire content of `/tmp/file.txt` into memory. - It divides the lines of the file into four chunks for processing in parallel. - Each thread processes its assigned chunk, counting the occurrences of each word and storing the results in a local `HashMap`. - After processing, each thread locks the shared `HashMap` to merge its results. - Finally, the counts are printed in JSON format. ### Compilation and Execution: To compile and run this program, save it to a file (e.g., `rust_word_count.rs`) and execute the following commands:

rustc rust_word_count.rs
./rust_word_count

This will print the word counts in the specified JSON format to standard output. Note that the output will be one JSON object per line, as per your request. You can then merge them as needed.

Here is a self-contained Rust program that reads a text file from `/tmp/file.txt`, counts the occurrences of each word in parallel using 4 threads, and prints the results in JSON format. This program does not use any external crates, so you can compile it directly with `rustc`.

use std::fs::File;

use std::sync::{Arc, Mutex};
use std::thread;
use std::collections::HashMap;

fn main() -> io::Result<()> {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path)?;
    let reader = io::BufReader::new(file);

    let total_lines = lines.len();

    // Create an Arc to share results between threads

    let mut handles = vec![];

    // Spawn 4 threads
    for i in 0..4 {
        let lines = lines.clone();
        let results = Arc::clone(&results);

        let handle = thread::spawn(move || {
            let mut local_count = HashMap::new();
            for line in &lines[start..end] {
                for word in line.split_whitespace() {

                    let cleaned_word = word.trim_matches(|c: char| !c.is_alphanumeric()).to_string();
                    if !cleaned_word.is_empty() {
                        *local_count.entry(cleaned_word).or_insert(0) += 1;
                    }

    Ok(())

### Explanation: 1. **Read from File**: The program reads all lines from `/tmp/file.txt` into a vector. 2. **Threading**: It spawns 4 threads, each responsible for processing a quarter of the lines. 3. **Counting Words**: Each thread counts the occurrences of words, cleaning them of punctuation and case sensitivity. 4. **Mutex**: A `Mutex` is used to safely share results between threads. 5. **JSON Output**: After all threads complete, the program prints each thread's result as a JSON object. ### Compilation and Execution: - Save the code to a file, e.g., `rust_word_count.rs`. - Compile it using:

  rustc rust_word_count.rs
  

- Run the program:

  ./rust_word_count
  

Make sure the file `/tmp/file.txt` exists and contains text for the program to process.

Output

Here's a self-contained Rust program that counts the occurrences of each word in a text file located at `/tmp/file.txt`. The program splits the file into four parts, processes each part in parallel, and outputs the word counts in JSON format, one JSON object per line. You can compile it with `rustc yourfile.rs` and run it as specified.

use std::collections::HashMap;
use std::fs::File;
use std::io::{BufRead, BufReader};
use std::sync::{Arc, Mutex};
use std::thread;

fn main() {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path).expect("Could not open file");
    let reader = BufReader::new(file);
    let lines: Vec<String> = reader.lines().filter_map(Result::ok).collect();
    let total_lines = lines.len();
    let chunk_size = (total_lines + 3) / 4; // Divide lines into 4 chunks

    let handles: Vec<_> = (0..4).map(|i| {
        let lines_clone = lines.clone();
        thread::spawn(move || {
            let mut word_count = HashMap::new();
            let start = i * chunk_size;
            let end = std::cmp::min(start + chunk_size, total_lines);
            for line in &lines_clone[start..end] {
                let words = line.split_whitespace();
                for word in words {
                    let cleaned_word = word.trim_matches(|c: char| !c.is_alphanumeric());
                    *word_count.entry(cleaned_word.to_string()).or_insert(0) += 1;
                }
            }
            word_count
        })
    }).collect();

    let mut results = Vec::new();
    for handle in handles {
        let word_count = handle.join().expect("Thread panicked");
        results.push(word_count);
    }

    for result in results {
        print_json(&result);
    }
}

fn print_json(word_count: &HashMap<String, usize>) {
    let json_str = word_count.iter()
        .map(|(key, value)| format!("\"{}\": {}", key, value))
        .collect::<Vec<_>>()
        .join(", ");
    println!("{{ {} }}", json_str);
}

### Explanation: 1. **Reading the File**: The program opens the file and reads its lines into a vector. 2. **Chunking**: It calculates the chunk size based on the total number of lines and divides the workload among four threads. 3. **Threading**: Each thread processes its portion of the lines, counting the occurrences of each word while cleaning punctuation. 4. **Output**: It formats the word counts as JSON strings and prints each JSON object on a new line. ### How to Compile and Run: 1. Save the code to a file, e.g., `rust_word_count.rs`. 2. Compile the program using:

   rustc rust_word_count.rs
   

3. Run the compiled executable:

   ./rust_word_count
   

Make sure that the file `/tmp/file.txt` exists and contains the text you want to analyze.

Extract Code

I extracted the following code from that output:

use std::collections::HashMap;
use std::fs::File;
use std::io::{BufRead, BufReader};
use std::sync::{Arc, Mutex};
use std::thread;

fn main() {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path).expect("Could not open file");
    let reader = BufReader::new(file);
    let lines: Vec<String> = reader.lines().filter_map(Result::ok).collect();
    let total_lines = lines.len();
    let chunk_size = (total_lines + 3) / 4; // Divide lines into 4 chunks

    let handles: Vec<_> = (0..4).map(|i| {
        let lines_clone = lines.clone();
        thread::spawn(move || {
            let mut word_count = HashMap::new();
            let start = i * chunk_size;
            let end = std::cmp::min(start + chunk_size, total_lines);
            for line in &lines_clone[start..end] {
                let words = line.split_whitespace();
                for word in words {
                    let cleaned_word = word.trim_matches(|c: char| !c.is_alphanumeric());
                    *word_count.entry(cleaned_word.to_string()).or_insert(0) += 1;
                }
            }
            word_count
        })
    }).collect();

    let mut results = Vec::new();
    for handle in handles {
        let word_count = handle.join().expect("Thread panicked");
        results.push(word_count);
    }

    for result in results {
        print_json(&result);
    }
}

fn print_json(word_count: &HashMap<String, usize>) {
    let json_str = word_count.iter()
        .map(|(key, value)| format!("\"{}\": {}", key, value))
        .collect::<Vec<_>>()
        .join(", ");
    println!("{{ {} }}", json_str);
}

Query

Below is some student's code. I asked them to parallelize some code. Do not judge if it is correct, I have test cases for that. Logic errors are okay. So are synatx errors. Just tell me if they tried to parallelize it. use std::collections::HashMap; use std::fs::File; use std::io::{BufRead, BufReader}; use std::sync::{Arc, Mutex}; use std::thread; fn main() { let file_path = "/tmp/file.txt"; let file = File::open(file_path).expect("Could not open file"); let reader = BufReader::new(file); let lines: Vec<String> = reader.lines().filter_map(Result::ok).collect(); let total_lines = lines.len(); let chunk_size = (total_lines + 3) / 4; // Divide lines into 4 chunks let handles: Vec<_> = (0..4).map(|i| { let lines_clone = lines.clone(); thread::spawn(move || { let mut word_count = HashMap::new(); let start = i * chunk_size; let end = std::cmp::min(start + chunk_size, total_lines); for line in &lines_clone[start..end] { let words = line.split_whitespace(); for word in words { let cleaned_word = word.trim_matches(|c: char| !c.is_alphanumeric()); *word_count.entry(cleaned_word.to_string()).or_insert(0) += 1; } } word_count }) }).collect(); let mut results = Vec::new(); for handle in handles { let word_count = handle.join().expect("Thread panicked"); results.push(word_count); } for result in results { print_json(&result); } } fn print_json(word_count: &HashMap<String, usize>) { let json_str = word_count.iter() .map(|(key, value)| format!("\"{}\": {}", key, value)) .collect::<Vec<_>>() .join(", "); println!("{{ {} }}", json_str); } Answer either 'The student passes' or 'The student fails'.

Run Code Interpreter

Running the following program:

use std::collections::HashMap;
use std::fs::File;
use std::io::{BufRead, BufReader};
use std::sync::{Arc, Mutex};
use std::thread;

fn main() {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path).expect("Could not open file");
    let reader = BufReader::new(file);
    let lines: Vec<String> = reader.lines().filter_map(Result::ok).collect();
    let total_lines = lines.len();
    let chunk_size = (total_lines + 3) / 4; // Divide lines into 4 chunks

    let handles: Vec<_> = (0..4).map(|i| {
        let lines_clone = lines.clone();
        thread::spawn(move || {
            let mut word_count = HashMap::new();
            let start = i * chunk_size;
            let end = std::cmp::min(start + chunk_size, total_lines);
            for line in &lines_clone[start..end] {
                let words = line.split_whitespace();
                for word in words {
                    let cleaned_word = word.trim_matches(|c: char| !c.is_alphanumeric());
                    *word_count.entry(cleaned_word.to_string()).or_insert(0) += 1;
                }
            }
            word_count
        })
    }).collect();

    let mut results = Vec::new();
    for handle in handles {
        let word_count = handle.join().expect("Thread panicked");
        results.push(word_count);
    }

    for result in results {
        print_json(&result);
    }
}

fn print_json(word_count: &HashMap<String, usize>) {
    let json_str = word_count.iter()
