Background
这是一道数学题!!!!!嘿嘿
Description
给你一组数列a1,a2,a3......an和一个数x。a1!+a2!.....+an!(数列每个数的阶乘之和)。使得阶乘之和可以整除x的阶乘;
(千万别被数据卡了qwq)
Input
第一行输入n(数列个数)和x;1≤n≤500000 , 1≤x≤500000) 第二行输入n个数;(ai<x)
Output
如果可以整除输出“Yes”,否则输出“No”;(无换行)
Samples
6 4
3 2 2 2 3 3
Yes
#列如第一个样例:3!+2!+2!+2!+3!+3!=6+2+2+2+6+6=24. 4!=24;可以整除。
