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
    for (uint8_t i = 0; i < n - 1; i++) {
        for (uint8_t j = 0; j < n - i - 1; j++) {
            if (arr[j] < arr[j+1]) {
               uint8_t temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j+1] = temp;
            }
        }
    }
// Print top 3 values
    uint8_t limit = (n < 3) ? n : 3;
    for (uint8_t i = 0; i < limit; i++) {
        printf("%hhu", arr[i]);
        if(i < limit-1){
            printf(" ");
        }
    }
}
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;
}
