+<h2><a href="https://leetcode.com/problems/plus-one/">66. Plus One</a></h2><h3>Easy</h3><hr><p>You are given a <strong>large integer</strong> represented as an integer array <code>digits</code>, where each <code>digits[i]</code> is the <code>i<sup>th</sup></code> digit of the integer. The digits are ordered from most significant to least significant in left-to-right order. The large integer does not contain any leading <code>0</code>&#39;s.</p>
+
+<p>Increment the large integer by one and return <em>the resulting array of digits</em>.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> digits = [1,2,3]
+<strong>Output:</strong> [1,2,4]
+<strong>Explanation:</strong> The array represents the integer 123.
+Incrementing by one gives 123 + 1 = 124.
+Thus, the result should be [1,2,4].
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> digits = [4,3,2,1]
+<strong>Output:</strong> [4,3,2,2]
+<strong>Explanation:</strong> The array represents the integer 4321.
+Incrementing by one gives 4321 + 1 = 4322.
+Thus, the result should be [4,3,2,2].
+</pre>
+
+<p><strong class="example">Example 3:</strong></p>
+
+<pre>
+<strong>Input:</strong> digits = [9]
+<strong>Output:</strong> [1,0]
+<strong>Explanation:</strong> The array represents the integer 9.
+Incrementing by one gives 9 + 1 = 10.
+Thus, the result should be [1,0].
+</pre>
+
+<p>&nbsp;</p>
+<p><strong>Constraints:</strong></p>
+
+<ul>
+	<li><code>1 &lt;= digits.length &lt;= 100</code></li>
+	<li><code>0 &lt;= digits[i] &lt;= 9</code></li>
+	<li><code>digits</code> does not contain any leading <code>0</code>&#39;s.</li>
+</ul>
