Rust | Array Example: Write a program to sort an array in descending order using bubble sort.
Submitted by Nidhi, on October 21, 2021

Problem Solution:

In this program, we will create an array of integer elements then we will sort the created array in descending order using bubble sort.

Program/Source Code:

The source code to sort an array in descending order using bubble sort is given below. The given program is compiled and executed successfully.

// Rust program to sort an array in 
// descending order using bubble sort

fn main() 
{
	let mut arr:[usize;5] = [5,1,11,23,26];
	let mut i:usize=0;
	let mut j:usize=0;
	let mut t:usize=0;

	println!("Array before sorting: {:?}",arr);

	while i<5
	{
		j=0;
		while j<(5-i-1)
		{
			if arr[j] < arr[j+1] 
			{
				t      = arr[j];
				arr[j] = arr[j+1];
				arr[j+1] = t;
			}
			j=j+1;
		}
		i=i+1;
	}

	println!("Array after sorting: {:?}",arr);
}

Output:

Array before sorting: [5, 1, 11, 23, 26]
Array after sorting: [26, 23, 11, 5, 1]

Explanation:

Here, we created an array of integers with 5 elements and then we sorted the created array in descending order using bubble sort. After that, we printed the sorted array.
