Algorithms

Given a list of <code>words</code>, list of&nbsp; single&nbsp;<code>letters</code> (might be repeating)&nbsp;and <code>score</code>&nbsp;of every character.

Return the maximum score of any valid set of words formed by using the given letters (<code>words[i]</code> cannot be used two&nbsp;or more times).

It is not necessary to use all characters in <code>letters</code> and each letter can only be used once. Score of letters&nbsp;<code>&#39;a&#39;</code>, <code>&#39;b&#39;</code>, <code>&#39;c&#39;</code>, ... ,<code>&#39;z&#39;</code> is given by&nbsp;<code>score[0]</code>, <code>score[1]</code>, ... , <code>score[25]</code> respectively.

Example 1:

<pre>
Input: words = [&quot;dog&quot;,&quot;cat&quot;,&quot;dad&quot;,&quot;good&quot;], letters = [&quot;a&quot;,&quot;a&quot;,&quot;c&quot;,&quot;d&quot;,&quot;d&quot;,&quot;d&quot;,&quot;g&quot;,&quot;o&quot;,&quot;o&quot;], score = [1,0,9,5,0,0,3,0,0,0,0,0,0,0,2,0,0,0,0,0,0,0,0,0,0,0]
Output: 23
Explanation:
Score a=1, c=9, d=5, g=3, o=2
Given letters, we can form the words &quot;dad&quot; (5+1+5) and &quot;good&quot; (3+2+2+5) with a score of 23.
Words &quot;dad&quot; and &quot;dog&quot; only get a score of 21.</pre>

Example 2:

<pre>
Input: words = [&quot;xxxz&quot;,&quot;ax&quot;,&quot;bx&quot;,&quot;cx&quot;], letters = [&quot;z&quot;,&quot;a&quot;,&quot;b&quot;,&quot;c&quot;,&quot;x&quot;,&quot;x&quot;,&quot;x&quot;], score = [4,4,4,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,0,10]
Output: 27
Explanation:
Score a=4, b=4, c=4, x=5, z=10
Given letters, we can form the words &quot;ax&quot; (4+5), &quot;bx&quot; (4+5) and &quot;cx&quot; (4+5) with a score of 27.
Word &quot;xxxz&quot; only get a score of 25.</pre>

Example 3:

<pre>
Input: words = [&quot;leetcode&quot;], letters = [&quot;l&quot;,&quot;e&quot;,&quot;t&quot;,&quot;c&quot;,&quot;o&quot;,&quot;d&quot;], score = [0,0,1,1,1,0,0,0,0,0,0,1,0,0,1,0,0,0,0,1,0,0,0,0,0,0]
Output: 0
Explanation:
Letter &quot;e&quot; can only be used once.</pre>
