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) {
    for (uint8_t i = 1; i < n; i++) {
        uint8_t key = arr[i];
        int j = i - 1;
        while (j >= 0 && arr[j] < key) {
            arr[j+1] = arr[j];
            j--;
        }
        arr[j+1] = key;
    }
    uint8_t num_print = (n < 3)? n: 3;
    for (uint8_t i = 0; i < num_print; i++)
        printf("%d ", arr[i]);
    printf("\n");
}

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;
}
