+<h2><a href="https://leetcode.com/problems/counter-ii/">2665. Counter II</a></h2><h3>Easy</h3><hr><div><p>Write a function&nbsp;<code>createCounter</code>. It should accept an initial integer&nbsp;<code>init</code>. It should return an object with three functions.</p>
+
+<p>The three functions are:</p>
+
+<ul>
+	<li><code>increment()</code>&nbsp;increases&nbsp;the current value by 1 and then returns it.</li>
+	<li><code>decrement()</code>&nbsp;reduces the current value by 1 and then returns it.</li>
+	<li><code>reset()</code>&nbsp;sets the current value to&nbsp;<code>init</code>&nbsp;and then returns it.</li>
+</ul>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre><strong>Input:</strong> init = 5, calls = ["increment","reset","decrement"]
+<strong>Output:</strong> [6,5,4]
+<strong>Explanation:</strong>
+const counter = createCounter(5);
+counter.increment(); // 6
+counter.reset(); // 5
+counter.decrement(); // 4
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre><strong>Input:</strong> init = 0, calls = ["increment","increment","decrement","reset","reset"]
+<strong>Output:</strong> [1,2,1,0,0]
+<strong>Explanation:</strong>
+const counter = createCounter(0);
+counter.increment(); // 1
+counter.increment(); // 2
+counter.decrement(); // 1
+counter.reset(); // 0
+counter.reset(); // 0
+</pre>
+
+<p>&nbsp;</p>
+<p><strong>Constraints:</strong></p>
+
+<ul>
+	<li><code>-1000 &lt;= init &lt;= 1000</code></li>
+	<li><code>0 &lt;= calls.length &lt;= 1000</code></li>
+	<li><code>calls[i]</code> is one of "increment", "decrement" and&nbsp;"reset"</li>
+</ul>
