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.

This program: 1. Reads the file into memory 2. Splits it into 4 chunks aligned to word boundaries 3. Processes each chunk in parallel using threads 4. Counts words in each chunk using a HashMap 5. Properly escapes JSON characters 6. Prints each chunk's result as a JSON object on a separate line 7. Uses only the Rust standard library 8. Handles special characters in words through proper JSON escaping The output will be 4 JSON objects (one per line) that you can merge. Each line represents the word count from a different chunk of the file. The program uses synchronized access to stdout to prevent interleaving of output.

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.
