Find Top 3 Largest Values in an Array

Code

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

void find_top_3(uint8_t *arr, uint8_t n) {
uint8_t count = (n < 3) ? n : 3;

    for (uint8_t i = 0; i < count; i++) 
    {
        uint8_t max_val = 0;
        uint8_t max_idx = 0xFF; 

        
        for (uint8_t j = 0; j < n; j++)
         {
            if (arr[j] > max_val)
             {
                max_val = arr[j];
                max_idx = j;
            }
        }

        if (max_idx != 0xFF) 
        {
            printf("%hhu ", max_val);
            arr[max_idx] = 0; 
        }
    }
}

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

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

    find_top_3(arr, n);
    return 0;
