Create a Rust program to sort an array of strings in lexicographical order

Question

Aryan Kumar · Answer

Sure, here is a Rust program to sort an array of strings in lexicographical order:

Rust

fn sort_strings(strings: &[String]) -> Vec<String> {
    let mut sorted_strings = strings.to_vec();
    sorted_strings.sort_by(|a, b| a.cmp(b));
    sorted_strings
}

fn main() {
    let strings = vec![
        String::from("hello"),
        String::from("world"),
        String::from("python"),
        String::from("programming"),
    ];

    let sorted_strings = sort_strings(&strings);

    println!("{:?}", sorted_strings);
}

This program first defines a function called sort_strings that takes an array of strings as input and returns a sorted vector of strings. The function uses the sort_by method to sort the strings in lexicographical order.

The main function of the program then creates an array of strings and calls the sort_strings function to sort the strings. The sorted strings are then printed to the console.

To run the program, you can save it as a file called sort_strings.rs and then compile it using the following command:

Code snippet

rustc sort_strings.rs

Once the program is compiled, you can run it using the following command:

Code snippet

./sort_strings

This will print the sorted strings to the console.
