Arcane Numbers 1

Vance and Shackler like playing games. One day, they are playing a game called "arcane numbers". The game is pretty simple, Vance writes down a finite decimal under base A, and then Shackler translates it under base B. If Shackler can translate it into a finite decimal, he wins, else it will be Vance’s win. Now given A and B, please help Vance to determine whether he will win or not. Note that they are playing this game using a mystery language so that A and B may be up to 10^12.

The first line contains a single integer T, the number of test cases.
For each case, there’s a single line contains A and B.

For each case, output “NO” if Vance will win the game. Otherwise, print “YES”. See Sample Output for more details.
