Let's define a function
f(s) over a non-empty string s, which calculates the frequency of the smallest character in s. For example, if s = "dcce" then f(s) = 2 because the smallest character is "c" and its frequency is 2.
Now, given string arrays
queries and words, return an integer array answer, where each answer[i] is the number of words such that f(queries[i]) < f(W), where W is a word in words.
Example 1:
Input: queries = ["cbd"], words = ["zaaaz"] Output: [1] Explanation: On the first query we have f("cbd") = 1, f("zaaaz") = 3 so f("cbd") < f("zaaaz").
Example 2:
Input: queries = ["bbb","cc"], words = ["a","aa","aaa","aaaa"] Output: [1,2] Explanation: On the first query only f("bbb") < f("aaaa"). On the second query both f("aaa") and f("aaaa") are both > f("cc").
class Solution: def numSmallerByFrequency(self, queries: List[str], words: List[str]) -> List[int]: answers = [] wordcount = sorted([word.count(min(word)) for word in words]) for query in queries: querycount = query.count(min(query)) pos = bisect.bisect(wordcount, querycount) answers.append(len(wordcount) - pos) return answers
