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:
letters
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]
。
示例 1:
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] 输出:23 解释: 字母得分为 a=1, c=9, d=5, g=3, o=2 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 。 而单词 "dad" 和 "dog" 只能得到 21 分。
示例 2:
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] 输出:27 解释: 字母得分为 a=4, b=4, c=4, x=5, z=10 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 。 单词 "xxxz" 的得分仅为 25 。
示例 3:
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] 输出:0 解释: 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。
提示:
1 <= words.length <= 14
1 <= words[i].length <= 15
1 <= letters.length <= 100
letters[i].length == 1
score.length == 26
0 <= score[i] <= 10
words[i]
和 letters[i]
只包含小写的英文字母。
