<p>You are given an integer array <code>coins</code> representing coins of different denominations and an integer <code>amount</code> representing a total amount of money.</p>
<p>Return <em>the fewest number of coins that you need to make up that amount</em>. If that amount of money cannot be made up by any combination of the coins, return <code>-1</code>.</p>
<p>You may assume that you have an infinite number of each kind of coin.</p>
<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>
<pre>
<strong>Input:</strong> coins = [1,2,5], amount = 11
<strong>Output:</strong> 3
<strong>Explanation:</strong> 11 = 5 + 5 + 1
</pre>
<p><strong class="example">Example 2:</strong></p>
<pre>
<strong>Input:</strong> coins = [2], amount = 3
<strong>Output:</strong> -1

<p><strong class="example">Example 3:</strong></p>
<pre>
<strong>Input:</strong> coins = [1], amount = 0
<strong>Output:</strong> 0

<p><strong>Constraints:</strong></p>
<ul>
<li><code>1 &lt;= coins.length &lt;= 12</code></li>
<li><code>1 &lt;= coins[i] &lt;= 2<sup>31</sup> - 1</code></li>
<li><code>0 &lt;= amount &lt;= 10<sup>4</sup></code></li>
