Given a list of words, list of single letters (might be repeating) and score of every character.
Return the maximum score of any valid set of words formed by using the given letters (words[i] cannot be used two or more times).
It is not necessary to use all characters in letters and each letter can only be used once. Score of letters 'a', 'b', 'c', ... ,'z' is given by score[0], score[1], ... , score[25] respectively.
\n
Example 1:
\n\n\nInput: words = ["dog","cat","dad","good"], letters = ["a","a","c","d","d","d","g","o","o"], 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]\nOutput: 23\nExplanation:\nScore a=1, c=9, d=5, g=3, o=2\nGiven letters, we can form the words "dad" (5+1+5) and "good" (3+2+2+5) with a score of 23.\nWords "dad" and "dog" only get a score of 21.\n\n
Example 2:
\n\n\nInput: words = ["xxxz","ax","bx","cx"], letters = ["z","a","b","c","x","x","x"], 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]\nOutput: 27\nExplanation:\nScore a=4, b=4, c=4, x=5, z=10\nGiven letters, we can form the words "ax" (4+5), "bx" (4+5) and "cx" (4+5) with a score of 27.\nWord "xxxz" only get a score of 25.\n\n
Example 3:
\n\n\nInput: words = ["leetcode"], letters = ["l","e","t","c","o","d"], 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]\nOutput: 0\nExplanation:\nLetter "e" can only be used once.\n\n

Constraints:
\n\n1 <= words.length <= 141 <= words[i].length <= 151 <= letters.length <= 100letters[i].length == 1score.length == 260 <= score[i] <= 10words[i], letters[i] contains only lower case English letters.你将会得到一份单词表 words，一个字母表 letters （可能会有重复字母），以及每个字母对应的得分情况表 score。
请你帮忙计算玩家在单词拼写游戏中所能获得的「最高得分」：能够由 letters 里的字母拼写出的 任意 属于 words 单词子集中，分数最高的单词集合的得分。
单词拼写游戏的规则概述如下：
\n\nletters 里的字母来拼写单词表 words 中的单词。letters 中的部分字母，但是每个字母最多被使用一次。words 中每个单词只能计分（使用）一次。score，字母 'a', 'b', 'c', ... , 'z' 对应的得分分别为 score[0], score[1], ..., score[25]。\n\n
示例 1：
\n\n输入：words = ["dog","cat","dad","good"], letters = ["a","a","c","d","d","d","g","o","o"], 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]\n输出：23\n解释：\n字母得分为 a=1, c=9, d=5, g=3, o=2\n使用给定的字母表 letters，我们可以拼写单词 "dad" (5+1+5)和 "good" (3+2+2+5)，得分为 23 。\n而单词 "dad" 和 "dog" 只能得到 21 分。\n\n
示例 2：
\n\n输入：words = ["xxxz","ax","bx","cx"], letters = ["z","a","b","c","x","x","x"], 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]\n输出：27\n解释：\n字母得分为 a=4, b=4, c=4, x=5, z=10\n使用给定的字母表 letters，我们可以组成单词 "ax" (4+5)， "bx" (4+5) 和 "cx" (4+5) ，总得分为 27 。\n单词 "xxxz" 的得分仅为 25 。\n\n
示例 3：
\n\n输入：words = ["leetcode"], letters = ["l","e","t","c","o","d"], 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]\n输出：0\n解释：\n字母 "e" 在字母表 letters 中只出现了一次，所以无法组成单词表 words 中的单词。\n\n
\n\n
提示：
\n\n1 <= words.length <= 141 <= words[i].length <= 151 <= letters.length <= 100letters[i].length == 1score.length == 260 <= score[i] <= 10words[i] 和 letters[i] 只包含小写的英文字母。\\u7248\\u672c\\uff1a
