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 var1 = -1, var2 = -1, var3 = -1; // use int, not uint8_t

    for (uint8_t i = 0; i < n; i++) {
        int num = arr[i];

        

        if (num > var1) {
            var3 = var2;
            var2 = var1;
            var1 = num;
        } 
        else if (num > var2 || var2 == -1) {
            var3 = var2;
            var2 = num;
        } 
        else if (num > var3 || var3 == -1) {
            var3 = num;
        }
    }

    if (var1 != -1) printf("%d ", var1);
    if (var2 != -1) printf("%d ", var2);
    if (var3 != -1) printf("%d", var3);
}

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;
}
