Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>

#define SIZE 3

int main() {
    int data[SIZE];
    int temp, i;
    int cnt5 = 2;
    int cnt7 = 1;

    temp = scanf("%d %d %d", &data[0], &data[1], &data[2]);

    for (i = 0; i < SIZE; i++)
    {
        if (data[i] == 5)
        {
            cnt5--;
        }
        else if (data[i] == 7)
        {
            cnt7--;
        }
    }
    if (cnt5 == 0 && cnt7 == 0) {
        puts("YES");
    }
    else {
