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.

import sys

G1 = [1, 3, 5, 7, 8, 10, 12]
G2 = [4, 6, 9, 11]

x,y = input().strip().split(' ')
x,y = [int(x),int(y)]

if x in G1 and y in G1:
    print("yes")
elif x in G2 and y in G2:
    print("yes")
else:
    print("no")
