• Problem Description

  
  Given a number , find whether it is a power of 2 or not
  
  NOTE There is a limit in Source code.
  Input
  
  The first Line contains T , the no of test cases followed by T lines.
  Each line has a integer X
  Output
  
  Output has T lines , with each line indicating whether the number is a power of 2 or not(print 1 if it a power of two else print 0).
