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) {
    uint8_t first,second,third, Ln = n;
    first = arr[0];
    second = first;
    third = first;
    while(Ln--){
        if(arr[Ln] > first){
            third = second;
            second = first;
            first = arr[Ln];
        }
        else if(arr[Ln] > second){
            third = second;
            second = arr[Ln];
        }
        else if(arr[Ln] > third){
            third = arr[Ln];
        }
    }
    if(n<=1){
        printf("%d", first);
    }
    else if ( n == 2 ){
        printf("%d %d", first, second);
    }
    else {
        printf("%d %d %d", first, second, third);
    }
}

int main() {

    scanf("%hhu", &n);
    uint8_t arr[100];

    for (uint8_t i = 0; i < n; i++) {
