PROBLEM:
Chef hosts a party for his birthday. There are N people at the party. All these N people decide to play Jenga.
There are X Jenga tiles available. In one round, all the players pick 1 tile each and place it in the tower.
The game is valid if:

All the players have a tile in each round;

All the tiles are used at the end.
Given N and X, find whether the game is valid.
EXPLANATION:
Let us assume it is a valid game that continues for M rounds then the number of tiles used will be N \times M as in each round a person will use 1 tile each. As we have to use all the tiles so we will get N \times M = X. We get the number of rounds by M = \frac{X}{N}.
Now we know for the game to be valid it should end after an integer number of rounds and its is only an integer if the number of tiles X is divisible by the number of players N. So, if it is divisible, then print YES otherwise print NO.
