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 a=-1,b=-1,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];
    }
   }
   if(a,b,c!=-1){printf("%d %d %d",a,b,c);}
   else if(a,b!=-1 && c==-1){printf("%d %d ",a,b);}
   else if(a!=-1 &&b,c==-1){printf("%d ",a);}
   else{
    
   }
   
}

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;
}
