description: 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: 
  
    * 34 can be turned into 81 via one operation: the binary form of 34 is 100010, if you add 1, reverse it and remove leading zeros, you will get 1010001, which is the binary form of 81. 
    * 34 can be turned into 17 via one operation: the binary form of 34 is 100010, if you add 0, reverse it and remove leading zeros, you will get 10001, which is the binary form of 17. 
    * 81 can be turned into 69 via one operation: the binary form of 81 is 1010001, if you add 0, reverse it and remove leading zeros, you will get 1000101, which is the binary form of 69. 
    * 34 can be turned into 69 via two operations: first you turn 34 into 81 and then 81 into 69. 
  
  
  
  Your task is to find out whether x can be turned into y after a certain number of operations (possibly zero).
  
  Input
  
  The only line of the input contains two integers x and y (1 ≤ x, y ≤ 10^{18}).
  
  Output
  
  Print YES if you can make x equal to y and NO if you can't.
