Problem Statement

Based on some criterion, Snuke divided the integers from 1 through 12 into three groups as shown in the figure below.
Given two integers x and y (1 ≤ x < y ≤ 12), determine whether they belong to the same group.

Constraints

x and y are integers.

1 ≤ x < y ≤ 12

Input

Input is given from Standard Input in the following format:

x y

Output

If x and y belong to the same group, print Yes; otherwise, print No.

Sample Input 1

1 3

Sample Output 1

Yes

Sample Input 2

2 4

Sample Output 2

No

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

#include<stdio.h>

int main()
{
	int i, j, k=-1, a, b, x[7] = { 1,3,5,7,8,10,12 }, y[4] = { 4,6,9.11 }, z = 2;

	scanf("%d %d", &a, &b);
	
	for (i = 0; i < 7;i++) {
		if (a == x[i]) k = 0;
	}
	if (k != 0) {
		for (i = 0;i < 4;i++) {
			if (a == y[i])k = 1;
		}
		if (k != 1) {
			k = 2;
		}
	}

	for (i = 0;i < 7;i++) {
		if (b == x[i]) j = 0;
	}
	if (j != 0) {
		for (i = 0;i < 4;i++) {
			if (b == y[i])j = 1;
		}
		if (j != 1) {
			j = 2;
		}
	}

	if (j == k) {
		printf("Yes\n");
	}
	else {
		printf("No\n");
	}

	return 0;
