Find Kth Smallest and Kth Largest Element

Code

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

void sort_array(uint8_t *a, uint8_t n) {
    // Sort in ascending order
    for(int i =0; i<n-1; i++)

        for(int j=i+1;j<n;j++)
        {

                a[j]=temp;
            }
        }
    }
}

void find_kth_elements(uint8_t *arr, uint8_t n, uint8_t k, uint8_t *smallest, uint8_t *largest) {
    // Your logic here
    *smallest = arr[k-1];
    *largest = arr[n-k];
}

int main() {
    uint8_t n, k;
    scanf("%hhu", &n);
    uint8_t arr[100];
    
    for (uint8_t i = 0; i < n; i++) {
        scanf("%hhu", &arr[i]);
    }

    scanf("%hhu", &k);
    sort_array(arr,n);
