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
  *a = *b = *c = -1;
    for (int i = 0; i < n; i++) {
        if (arr[i] > *a) {
            *c = *b;
            *b = *a;
            *a = arr[i];
        } else if (arr[i] > *b) {
            *c = *b;
            *b = arr[i];
        } else if (arr[i] > *c) {
            *c = 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;
}
