1160 - Find Words That Can Be Formed by Characters.<p>Easy</p>
<p>You are given an array of strings <code>words</code> and a string <code>chars</code>.</p>
<p>A string is <strong>good</strong> if it can be formed by characters from chars (each character can only be used once).</p>
<p>Return <em>the sum of lengths of all good strings in words</em>.</p>
<p><strong>Example 1:</strong></p>
<p><strong>Input:</strong> words = [“cat”,“bt”,“hat”,“tree”], chars = “atach”</p>
<p><strong>Output:</strong> 6</p>
<p><strong>Explanation:</strong> The strings that can be formed are “cat” and “hat” so the answer is 3 + 3 = 6.</p>
<p><strong>Example 2:</strong></p>
<p><strong>Input:</strong> words = [“hello”,“world”,“leetcode”], chars = “welldonehoneyr”</p>
<p><strong>Output:</strong> 10</p>

<p><strong>Constraints:</strong></p>
<ul>
<li><code>1 <= words.length <= 1000</code></li>
<li><code>1 <= words[i].length, chars.length <= 100</code></li>
