/*
 * 189. Rotate Array
 * Difficulty: Medium
 * https://leetcode.com/problems/rotate-array/
 * 
 * ──────────────────────────────────────────────────
 * 
 * Given an integer array nums, rotate the array to the right by k
 * steps, where k is non-negative.
 * 
 *  
 * 
 * Example 1:
 * 
 * Input: nums = [1,2,3,4,5,6,7], k = 3
 * Output: [5,6,7,1,2,3,4]
 * Explanation:
 * rotate 1 steps to the right: [7,1,2,3,4,5,6]
 * rotate 2 steps to the right: [6,7,1,2,3,4,5]
 * rotate 3 steps to the right: [5,6,7,1,2,3,4]
 * 
 * Example 2:
 * 
 * Input: nums = [-1,-100,3,99], k = 2
 * Output: [3,99,-1,-100]
 * Explanation: 
 * rotate 1 steps to the right: [99,-1,-100,3]
 * rotate 2 steps to the right: [3,99,-1,-100]
 * 
 *  
 * 
 * Constraints:
 * 
 * 	• 1 <= nums.length <= 10^5
 * 
 * 	• -2^31 <= nums[i] <= 2^31 - 1
 * 
 * 	• 0 <= k <= 10^5
 * 
 *  
 * 
 * Follow up:
 * 
 * • Try to come up with as many solutions as you can. There are at
 * least three different ways to solve this problem.
 * 
 * 	• Could you do it in-place with O(1) extra space?
