A non-negative integer 'num' is passed in as a parameter. Your goal is to determine the bitwise parity of the binary representation of that number. For example, 5, in binary is 101. That binary representation has a even number of 1's and therefore has even parity. Write a method that returns 'true' if 'num' has even pairty or 'false' if 'num' has odd pairty. Note that this is NOT about whether 'num' is an even number or not. It IS about the number of 1's in the binary representation of 'num'.
