Find Kth Smallest and Kth Largest Element

Code

#include <stdio.h>
#include <stdint.h>

void sort_array(uint8_t *arr, uint8_t n) {
    bool swapped = true;; 
    while (swapped){ 
        swapped = false; 
        for (int i = 0; i < n - 1; i++){ 
            if (arr[i] > arr[i + 1]){ 
                int temp = arr[i];
                arr[i] = arr[i+1]; 
                arr[i+1] = temp; 
                swapped = true;  
            }
        }
    }

}

    sort_array(arr, n);
