Rust Program to Compute all the permutations of the string

Compute all the permutations of the string

Rust Programming Language

Problem

In Rust, we can use the itertools crate to compute all the permutations of a given string. Here's an example program that demonstrates how to do this.

Input

use itertools::Itertools;

fn main() {

    let input = "abc";

    let permutations = input.chars().permutations(input.len());

    for permutation in permutations {

        let string = permutation.into_iter().collect::<String>();

        println!("{}", string);

    }

}{codeBox}

Output

The output of this program will be all the permutations of the input string "abc", in this case:

abc

acb

bac

bca

cab

cba{codeBox}

Explanation

In this program, we first import the Itertools trait from the itertools crate. We then define a String input variable containing the string for which we want to compute permutations.

Next, we use the chars() method to convert the input string into an iterator of characters. We then call the permutations() method on the iterator, passing in the length of the input string. This generates an iterator of permutations of the input string.

We then loop through each permutation and convert it back into a string using the into_iter() and collect() methods. Finally, we print the resulting string to the console.
