{ "data": { "question": { "questionId": "1273", "questionFrontendId": "1170", "categoryTitle": "Algorithms", "boundTopicId": 22197, "title": "Compare Strings by Frequency of the Smallest Character", "titleSlug": "compare-strings-by-frequency-of-the-smallest-character", "content": "

Let the function f(s) be the frequency of the lexicographically smallest character in a non-empty string s. For example, if s = "dcce" then f(s) = 2 because the lexicographically smallest character is 'c', which has a frequency of 2.

\n\n

You are given an array of strings words and another array of query strings queries. For each query queries[i], count the number of words in words such that f(queries[i]) < f(W) for each W in words.

\n\n

Return an integer array answer, where each answer[i] is the answer to the ith query.

\n\n

 

\n

Example 1:

\n\n
\nInput: queries = ["cbd"], words = ["zaaaz"]\nOutput: [1]\nExplanation: On the first query we have f("cbd") = 1, f("zaaaz") = 3 so f("cbd") < f("zaaaz").\n
\n\n

Example 2:

\n\n
\nInput: queries = ["bbb","cc"], words = ["a","aa","aaa","aaaa"]\nOutput: [1,2]\nExplanation: On the first query only f("bbb") < f("aaaa"). On the second query both f("aaa") and f("aaaa") are both > f("cc").\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "比较字符串最小字母出现频次", "translatedContent": "

定义一个函数 f(s),统计 s  中(按字典序比较)最小字母的出现频次 ,其中 s 是一个非空字符串。

\n\n

例如,若 s = \"dcce\",那么 f(s) = 2,因为字典序最小字母是 \"c\",它出现了 2 次。

\n\n

现在,给你两个字符串数组待查表 queries 和词汇表 words 。对于每次查询 queries[i] ,需统计 words 中满足 f(queries[i]) < f(W) 的 词的数目W 表示词汇表 words 中的每个词。

\n\n

请你返回一个整数数组 answer 作为答案,其中每个 answer[i] 是第 i 次查询的结果。

\n\n

 

\n\n

示例 1:

\n\n
\n输入:queries = [\"cbd\"], words = [\"zaaaz\"]\n输出:[1]\n解释:查询 f(\"cbd\") = 1,而 f(\"zaaaz\") = 3 所以 f(\"cbd\") < f(\"zaaaz\")。\n
\n\n

示例 2:

\n\n
\n输入:queries = [\"bbb\",\"cc\"], words = [\"a\",\"aa\",\"aaa\",\"aaaa\"]\n输出:[1,2]\n解释:第一个查询 f(\"bbb\") < f(\"aaaa\"),第二个查询 f(\"aaa\") 和 f(\"aaaa\") 都 > f(\"cc\")。\n
\n\n
