1170. Compare Strings by Frequency of the Smallest Character ¶
Problem
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.
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
.
Return an integer array answer
, where each answer[i]
is the answer to the ith
query.
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").
Constraints:
1 <= queries.length <= 2000
1 <= words.length <= 2000
1 <= queries[i].length, words[i].length <= 10
queries[i][j]
,words[i][j]
consist of lowercase English letters.
