Find Kth Smallest and Kth Largest Element

Code

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

void sort_array(uint8_t *arr, uint8_t n) {
    // Sort in ascending ordernyg b
       int temp,i,j,k=0;
    for( i=1;i<n;i++){
        temp=arr[i];
        j=i-1;
        while(j>=0 && arr[j]>temp){
            arr[j+1]=arr[j];
            j--;
        }
        arr[j+1]=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);

    uint8_t smallest, largest;
    sort_array(arr,n);
    find_kth_elements(arr, n, k, &smallest, &largest);
   
    printf("%hhu %hhu", smallest, largest);
