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) {
    // Your logic here
    int max_print = 3;
    if(n<max_print) max_print = n;
    for (uint8_t i = 0; i < max_print; i++) {
        for (uint8_t j = i + 1; j < n; j++) {
            if (arr[i] < arr[j]) {
                uint8_t temp = arr[i];
                arr[i] = arr[j];
                arr[j] = temp;
            }
        }
    printf("%d ",arr[i]);
    }
}

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;
}
