I have setup the docker container to run the model evaluation.
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 Do not import serde_json, write json output from scratch.

Here is a self-contained Rust program that reads a text file located at `/tmp/file.txt`, counts the occurrences of each word, and prints the result as a JSON object to stdout:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | use std::collections::HashMap; use std::fs; use std::io; fn main() -> io::Result<()> { // Read the file content let content = fs::read_to_string("/tmp/file.txt")?; // Split the content into words and count occurrences let mut word_count = HashMap::new(); for word in content.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } // Generate JSON output let mut json_output = String::from("{"); for (i, (word, count)) in word_count.iter().enumerate() { if i > 0 { json_output.push_str(", "); } json_output.push_str(&format!("\"{}\": {}", word, count)); } json_output.push('}'); // Print the JSON output println!("{}", json_output); Ok(()) } |
1 | This is is is, an example |
1 | {"This": 1, "is": 2, "is,": 1, "an": 1, "example": 1} |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | use std::collections::HashMap; use std::fs; use std::io; fn main() -> io::Result<()> { // Read the file content let content = fs::read_to_string("/tmp/file.txt")?; // Split the content into words and count occurrences let mut word_count = HashMap::new(); for word in content.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } // Generate JSON output let mut json_output = String::from("{"); for (i, (word, count)) in word_count.iter().enumerate() { if i > 0 { json_output.push_str(", "); } json_output.push_str(&format!("\"{}\": {}", word, count)); } json_output.push('}'); // Print the JSON output println!("{}", json_output); Ok(()) } |
Running the following program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | use std::collections::HashMap; use std::fs; use std::io; fn main() -> io::Result<()> { // Read the file content let content = fs::read_to_string("/tmp/file.txt")?; // Split the content into words and count occurrences let mut word_count = HashMap::new(); for word in content.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } // Generate JSON output let mut json_output = String::from("{"); for (i, (word, count)) in word_count.iter().enumerate() { if i > 0 { json_output.push_str(", "); } json_output.push_str(&format!("\"{}\": {}", word, count)); } json_output.push('}'); // Print the JSON output println!("{}", json_output); Ok(()) } |

I extracted the following JSON from that output:
1 | {"best": 1, "hope,": 1, "before": 2, "foolishness,": 1, "nothing": 1, "age": 2, "despair,": 1, "other": 1, "were": 2, "epoch": 2, "worst": 1, "belief,": 1, "to": 1, "of": 10, "had": 2, "Darkness,": 1, "Heaven,": 1, "wisdom,": 1, "spring": 1, "we": 4, "was": 10, "it": 10, "times,": 2, "Light,": 1, "us,": 2, "way": 1, "all": 2, "season": 2, "the": 11, "winter": 1, "going": 2, "direct": 2, "incredulity,": 1, "everything": 1} |
Testing if the previous output matches the JSON: {

"we": 4,
