    693 - Binary Number with Alternating Bits\.

    Easy

    Given a positive integer, check whether it has alternating bits: namely, if two adjacent bits will always have different values.

    Example 1:

    Input: n = 5

    Output: true

    Explanation: The binary representation of 5 is: 101

    Example 2:

    Input: n = 7

    Output: false

    Explanation: The binary representation of 7 is: 111.

    Example 3:

    Input: n = 11

    Output: false

    Explanation: The binary representation of 11 is: 1011.
