Rust program to swap adjacent elements of the array

Rust | Array Sorting: Write a program to swap adjacent elements of the array.
Last Updated : October 22, 2021

Problem Statement

In this program, we will create an array of integers then we will swap the adjacent elements of the array and print the updated array.

Program/Source Code

The source code to swap adjacent elements of the array is given below. The given program is compiled and executed successfully.

// Rust program to swap adjacent elements 
// of the array

fn main() 
{
    let mut arr:[usize;6] = [0,1,2,3,4,5];
    let mut i:usize=0;
    let mut temp:usize=0;
    
    println!("Array before swapping: {:?}",arr);
    
    // Swap adjacent elements
    while i<=4
    {
        temp = arr[i];
        arr[i] = arr[i+1];
        arr[i+1] = temp;
        i = i + 2;
    }
    
    println!("Array after swapping: {:?}",arr);
}

Output

Array before swapping: [0, 1, 2, 3, 4, 5]
Array after swapping: [1, 0, 3, 2, 5, 4]

Explanation

Here, we created an array of integers with 6 elements, and then we swapped the adjacent elements of the array. After that, we printed the updated array.
