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
    uint8_t count = (n < 3) ? n : 3;

    for(int j=0; j < count; j++){
        int max_idx = j;

        for(int i=j+1;i < n;i++){
            if(arr[i] > arr[max_idx]){
                max_idx = i;
            }
        }
        if(max_idx !=j){
            int temp = arr[j];
            arr[j] = arr[max_idx];
            arr[max_idx] = temp;
        }
        printf("%d ",arr[j]);
    }
}

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;
}

Solving Approach

Partial sort only top 3 elements and leave the remaining array unsorted
