Find Top 3 Largest Values in an Array

Code

#include <stdio.h>
#include <stdint.h>

void bubble_sort_desc(uint8_t *arr, uint8_t n) {
    // Your logic here
    uint8_t i, j, localmax, hold;
    for (i=0; i < n-1; i++) {
        localmax= i; // top position
        for (j=i; j < n; j++) {
            if (arr[j] > arr[localmax]) {
                localmax = j;
            }
        }
        hold = arr[i];
        arr[i] = arr[localmax];
        arr[localmax] = hold;
    }
}

void find_top_3(uint8_t *arr, uint8_t n) {
    // Your logic here
    bubble_sort_desc(arr, n);
    uint8_t i;
    for (i=0; ((i < 3) && (i < n)); i++)
        printf("%hu ", 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;
}

Solving Approach

Use the bubble_sort_desc I wrote in preceding example and sort the array.

then print the top elements (up to three).
