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.

Certainly! You can use the following Rust program to achieve the desired output. This example reads a text file, counts occurrences of each word, and outputs the counts in JSON format. Note that it does not use external crates for JSON serialization; instead, it constructs the JSON string manually. Please save the following code to a Rust source file, for example, `rust_word_count.rs`:
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 30 31 32 33 34 35 | use std::collections::HashMap; use std::fs::File; use std::io::{self, BufRead}; use std::path::Path; fn main() -> io::Result<()> { let path = "/tmp/file.txt"; let input = File::open(path)?; let buffered = io::BufReader::new(input); let mut word_count = HashMap::new(); for line in buffered.lines() { let line = line?; for word in line.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } } // Begin JSON output print!("{{"); let mut first = true; for (word, count) in word_count { if !first { print!(","); } first = false; // Escape double quotes and backslashes in the word let escaped_word = word.replace("\\", "\\\\").replace("\"", "\\\""); print!("\"{}\": {}", escaped_word, count); } println!("}}"); Ok(()) } |
1 2 | rustc rust_word_count.rs |
1 2 | echo "This is is is, an example" > /tmp/file.txt |

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 30 31 32 33 34 35 | use std::collections::HashMap; use std::fs::File; use std::io::{self, BufRead}; use std::path::Path; fn main() -> io::Result<()> { let path = "/tmp/file.txt"; let input = File::open(path)?; let buffered = io::BufReader::new(input); let mut word_count = HashMap::new(); for line in buffered.lines() { let line = line?; for word in line.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } } // Begin JSON output print!("{{"); let mut first = true; for (word, count) in word_count { if !first { print!(","); } first = false; // Escape double quotes and backslashes in the word let escaped_word = word.replace("\\", "\\\\").replace("\"", "\\\""); print!("\"{}\": {}", escaped_word, count); } println!("}}"); Ok(()) } |

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.

Below is a self-contained Rust program that reads from a file located at `/tmp/file.txt`, counts the occurrences of each word, and prints the result in JSON format. This program does not use any external crates, so you can compile it with `rustc` directly and run it without any arguments.
