# 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.
