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.

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::{ fs::File, io::{self, BufRead}, path::Path, sync::mpsc, thread, }; fn main() { let file_path = Path::new("/tmp/file.txt"); let file = File::open(file_path).expect("Could not open file"); let file_content = io::BufReader::new(file); let (tx1, rx1) = mpsc::channel(); let (tx2, rx2) = mpsc::channel(); let (tx3, rx3) = mpsc::channel(); let (tx4, rx4) = mpsc::channel(); // Split the file into 4 chunks and send them to the threads let mut lines = file_content.lines(); let mut chunk_size = 0; let mut lines_sent = 0; for line in lines.by_ref() { if chunk_size == 0 { chunk_size = line.as_ref().unwrap().len() / 4; } if lines_sent < chunk_size { tx1.send(line.unwrap()).unwrap(); lines_sent += 1; } else if lines_sent < chunk_size * 2 { tx2.send(line.unwrap()).unwrap(); lines_sent += 1; } else if lines_sent < chunk_size * 3 { tx3.send(line.unwrap()).unwrap(); lines_sent += 1; } else { tx4.send(line.unwrap()).unwrap(); lines_sent = 0; } } // Start the threads let t1 = thread::spawn(move || word_count(rx1)); let t2 = thread::spawn(move || word_count(rx2)); let t3 = thread::spawn(move || word_count(rx3)); let t4 = thread::spawn(move || word_count(rx4)); // Join the threads let r1 = t1.join().unwrap(); let r2 = t2.join().unwrap(); let r3 = t3.join().unwrap(); let r4 = t4.join().unwrap(); println!("{}", r1); println!("{}", r2); println!("{}", r3); println!("{}", r4); } fn word_count(rx: mpsc::Receiver<String>) -> String { let mut word_counts: std::collections::HashMap<String, i32> = std::collections::HashMap::new(); for line in rx.iter() { let words = line.split_whitespace(); for word in words { let word = word.to_lowercase(); let count = word_counts.entry(word).or_insert(0); *count += 1; } } let json = serde_json::json!(&word_counts); json.to_string() } Answer either 'The student passes' or 'The student fails'.

Run Code Interpreter

Running the following program:

use std::{
    env,
    fs::File,
    io::{BufRead, BufReader},
    sync::{Arc, Mutex},
    thread,

fn main() {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path).unwrap();
    let reader = BufReader::new(file);

    // Count words in parallel
    let num_threads = 4;
    let lines_per_thread = reader.lines().count() / num_threads;
    let mut handles = Vec::new();
    let counts = Arc::new(Mutex::new(vec![0; 1000]));

    for i in 0..num_threads {
        let start = i * lines_per_thread;
        let end = (i + 1) * lines_per_thread;
        let counts = Arc::clone(&counts);
        let handle = thread::spawn(move || {
            let mut counts = counts.lock().unwrap();
            let lines = reader.lines().skip(start).take(end);
            for line in lines {

                for word in line.split_whitespace() {
