How to Shuffle an Array in Rust ?

Answer

In Rust, you can shuffle an array using the rand crate's Fisher-Yates shuffle algorithm.

✐ Examples

1 Shuffle Array of Integers

In this example,

We have an array named intArray containing integers.
We apply the Fisher-Yates shuffle algorithm to intArray.
We print the shuffled array to demonstrate the shuffling.

Rust Program

extern crate rand;
use rand::seq::SliceRandom;
fn main() {
    let mut int_array = [1, 2, 3, 4, 5];
    let mut rng = rand::thread_rng();
    int_array.shuffle(&mut rng);
    println!("Shuffled Array: {:?}", int_array);
}

Output

Shuffled Array: [3, 4, 1, 5, 2]

2 Shuffle Array of Strings

In this example,

We have an array named str_array containing strings.
We apply the Fisher-Yates shuffle algorithm to str_array.
We print the shuffled array to demonstrate the shuffling.

Rust Program

extern crate rand;
use rand::seq::SliceRandom;
fn main() {
    let mut str_array = ["apple", "banana", "cherry"];
    let mut rng = rand::thread_rng();
    str_array.shuffle(&mut rng);
    println!("Shuffled Array: {:?}", str_array);
}

Output

Shuffled Array: ["cherry", "apple", "banana"]
