B"You are given two positive integers x and y . You can perform the following operation with x : write it in its binary form without leading zeros, add 0 or 1 to the right of it, reverse the binary form and turn it into a decimal number which is assigned as the new value of x . For example: Your task is to find out whether x can be turned into y after a certain number of operations (possibly zero). The only line of the input contains two integers x and y ( 1 <= x, y <= 10^{18} ). Print YES if you can make x equal to y and NO if you can't. In the first example, you don't even need to do anything. The fourth example is described in the statement. "...
