Rust program to sort an array in descending order using selection sort

Rust | Array Sorting: Write a program to sort an array in descending order using selection sort.
Submitted by Nidhi, on October 22, 2021

Problem Solution:

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

Program/Source Code:

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

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

fn main() 
{
    	let mut arr:[usize;5] = [5,1,23,11,26];
    	let mut i:usize=0;
    	let mut j:usize=0;
    
    	let mut min:usize=0;
    	let mut temp:usize=0;
    
    	println!("Array before sorting: {:?}",arr);

    	while i <= 4 
    	{
		min = i;
		j   = i + 1; 
		
		while j <= 4 
		{
			if arr[j] > arr[min] {
				min = j;
			}
			j=j+1; 
		}
		temp = arr[i];
		arr[i] = arr[min];
		arr[min] = temp;
		
		i=i+1;
	}
	println!("Array after sorting: {:?}",arr);
}

Output:

Array before sorting: [5, 1, 23, 11, 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 selection sort. After that, we printed the sorted array.
