B'You are given an integer x and an array of integers a_1, a_2, ldots, a_n . You have to determine if the number a_1! + a_2! + ldots + a_n! is divisible by x! . Here k! is a factorial of k -- the product of all positive integers less than or equal to k . For example, 3! = 1 cdot 2 cdot 3 = 6 , and 5! = 1 cdot 2 cdot 3 cdot 4 cdot 5 = 120 . The first line contains two integers n and x ( 1 <= n <= 500 ,000 , 1 <= x <= 500 ,000 ). The second line contains n integers a_1, a_2, ldots, a_n ( 1 <= a_i <= x ) -- elements of given array. In the only line print "Yes" (without quotes) if a_1! + a_2! + ldots + a_n! is divisible by x! , and "No" (without quotes) otherwise. In the first example 3! + 2! + 2! + 2! + 3! + 3! = 6 + 2 + 2 + 2 + 6 + 6 = 24 . Number 24 is divisible by 4! = 24 . In the second example 3! + 2! + 2! + 2! + 2! + 2! + 1! + 1! = 18 , is divisible by 3! = 6 . In the third example 7! + 7! + 7! + 7! + 7! + 7! + 7! = 7 cdot 7! . It is easy to prove that this number is not divisible by 8! . '...
