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.
