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.

This program: 1. Reads the entire file into memory (works well for small-to-medium files) 2. Splits the text into words using Unicode-aware whitespace splitting 3. Divides the words into 4 chunks as evenly as possible 4. Processes each chunk in parallel using threads 5. Counts word frequencies in each chunk 6. Outputs JSON dictionaries with proper escaping 7. Uses a mutex to ensure clean line-by-line output 8. Sorts entries for deterministic output ordering To compile and run: 
1
2
rustc rust_word_count.rs
./rust_word_count
The program will print 4 JSON dictionaries (one per line) containing word counts from different chunks of the file. Note that: - Words are split according to Unicode whitespace - Punctuation stays attached to words (as in your example) - Output is sorted lexicographically for consistency - The merging of results is left to the caller as requested

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::Read; use std::sync::Mutex; fn main() -> std::io::Result<()> { let path = "/tmp/file.txt"; let mut content = String::new(); File::open(path)?.read_to_string(&mut content)?; let words: Vec<&str> = content.split_whitespace().collect(); let total_words = words.len(); let num_chunks = 4; let quot = total_words / num_chunks; let rem = total_words % num_chunks; let mut chunks = Vec::new(); let mut start = 0; for i in 0..num_chunks { let chunk_size = quot + if i < rem { 1 } else { 0 }; let end = (start + chunk_size).min(total_words); chunks.push(&words[start..end]); start = end; } let stdout = Mutex::new(std::io::stdout()); std::thread::scope(|s| { for chunk in chunks { s.spawn(|| { let mut counts = HashMap::new(); for &word in chunk { *counts.entry(word.to_string()).or_insert(0) += 1; } let json = format_counts(&counts); let mut stdout = stdout.lock().unwrap(); println!("{}", json); }); } }); Ok(()) } fn format_counts(counts: &HashMap<String, u32>) -> String { let mut entries: Vec<String> = counts .iter() .map(|(word, count)| { let escaped = word .chars() .map(|c| match c { '"' => "\\\"".to_string(), '\\' => "\\\\".to_string(), _ => c.to_string(), }) .collect::<String>(); format!("\"{}\": {}", escaped, count) }) .collect(); entries.sort(); format!("{{{}}}", entries.join(", ")); } Answer either 'The student passes' or 'The student fails'.
