Given a positive integer, check whether it has alternating bits: namely,   if two adjacent bits will always have different values.       For example:   Input: 5   Output: True because the binary representation of 5 is: 101.       Input: 7   Output: False because the binary representation of 7 is: 111.       Input: 11   Output: False because the binary representation of 11 is: 1011.       Input: 10   Output: True because The binary representation of 10 is: 1010.

Question
Given a positive integer, check whether it has alternating bits: namely,
  if two adjacent bits will always have different values.
   
  For example:
  Input: 5
  Output: True because the binary representation of 5 is: 101.
   
  Input: 7
  Output: False because the binary representation of 7 is: 111.
   
  Input: 11
  Output: False because the binary representation of 11 is: 1011.
   
  Input: 10
  Output: True because The binary representation of 10 is: 1010.
