Problem Statement

AtCoDeer has three cards, one red, one green and one blue.

An integer between 1 and 9 (inclusive) is written on each card: r on the red card, g on the green card and b on the blue card.

We will arrange the cards in the order red, green and blue from left to right, and read them as a three-digit integer.

Is this integer a multiple of 4?

Constraints

1 ≤ r, g, b ≤ 9

Input

Input is given from Standard Input in the following format:

r g b

Output

If the three-digit integer is a multiple of 4, print YES (case-sensitive); otherwise, print NO.

Sample Input 1

4 3 2

Sample Output 1

YES

432 is a multiple of 4, and thus YES should be printed.

Sample Input 2

2 3 4

Sample Output 2

NO

234 is not a multiple of 4, and thus NO should be printed.

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main()
{
	int n, i, c[8] = { 0 };
	int a[100], wild = 0;
	int max, min;
	max = min = 0;

	scanf("%d", &n);

	for (i = 0; i < n; i++){
		scanf("%d", &a[i]);
		if (a[i] >= 3200)
			wild++;
		else if (a[i] >= 2800)
			c[7] = 1;
		else if (a[i] >= 2400)
			c[6] = 1;
		else if (a[i] >= 2000)
			c[5] = 1;
		else if (a[i] >= 1600)
			c[4] = 1;
		else if (a[i] >= 1200)
			c[3] = 1;
		else if (a[i] >= 800)
			c[2] = 1;
		else if (a[i] >= 400)
			c[1] = 1;
		else
			c[0] = 1;
	}

	for (i = 0; i < 8; i++){
		if (c[i] == 1)
			min++;
	}
	max = min + wild;
	if (min == 0)
		min = 1;
	printf("%d %d", min, max);

	return 0;
