Understanding the Compare Strings by Frequency of the Smallest Character Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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.

How Interview Coder Helps
Get real-time assistance for Compare Strings by Frequency of the Smallest Character problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
queries = ["cbd"], words = ["zaaaz"][1]On the first query we have f("cbd") = 1, f("zaaaz") = 3 so f("cbd") < f("zaaaz").
queries = ["bbb","cc"], words = ["a","aa","aaa","aaaa"][1,2]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 <= 20001 <= words.length <= 20001 <= queries[i].length, words[i].length <= 10queries[i][j], words[i][j] consist of lowercase English letters.How Interview Coder Helps with Leetcode Problems
