<h2>189. Rotate Array</h2><h3>Medium</h3><hr><div><p>Given an array, rotate the array to the right by <code>k</code> steps, where <code>k</code> is non-negative.</p>

<p>&nbsp;</p>

<p><strong>Example 1:</strong></p>

<pre><strong>Input:</strong> nums = [1,2,3,4,5,6,7], k = 3

<strong>Output:</strong> [5,6,7,1,2,3,4]

<strong>Explanation:</strong>

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]

</pre>

<p><strong>Example 2:</strong></p>

<pre><strong>Input:</strong> nums = [-1,-100,3,99], k = 2

<strong>Output:</strong> [3,99,-1,-100]

<strong>Explanation:</strong>

rotate 1 steps to the right: [99,-1,-100,3]

rotate 2 steps to the right: [3,99,-1,-100]

</pre>

<p>&nbsp;</p>

<p><strong>Constraints:</strong></p>

<ul>

<li><code>1 &lt;= nums.length &lt;= 10⁵</code></li>

<li><code>-2³¹ &lt;= nums[i] &lt;= 2³¹ - 1</code></li>

<li><code>0 &lt;= k &lt;= 10⁵</code></li>

</ul>

<p>&nbsp;</p>

<p><strong>Follow up:</strong></p>

<ul>

<li>Try to come up with as many solutions as you can. There are at least <strong>three</strong> different ways to solve this problem.</li>

<li>Could you do it in-place with <code>O(1)</code> extra space?</li>

</ul>
