Sort an Array in Descending Order

Code

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

void bubble_sort_desc(uint8_t *arr, uint8_t n) {
    
    uint8_t global_idx = 0;
    uint8_t max_value = arr[0];
    uint8_t tmp_idx;

    while (global_idx < n) {
        for (uint8_t idx = global_idx; idx < n; idx++) {
            if (arr[idx] >= max_value) {
                max_value = arr[idx];
                tmp_idx = idx;
            }
        }
        arr[tmp_idx] = arr[global_idx];
        arr[global_idx++] = max_value;
        max_value = arr[global_idx];
    }
}

int main() {
    uint8_t n;
    scanf("%hhu", &n);
    uint8_t arr[100];

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

    bubble_sort_desc(arr, n);

    for (uint8_t i = 0; i < n; i++) {
        printf("%hhu", arr[i]);
        if(i < n-1){
            printf(" ");
        }
    }

    return 0;
