Subsets Leetcode A string b is a subset of string a if every letter in b occurs in a including multiplicity. for example, "wrr" is a subset of "warrior" but is not a subset of "world". In depth solution and explanation for leetcode 916. word subsets in python, java, c and more. intuitions, example walk through, and complexity analysis. better than official and forum solutions.
Subsets Leetcode Problem 78 Python Solution Description you are given two string arrays words1 and words2. a string b is a subset of string a if every letter in b occurs in a including multiplicity. Leetcode solutions in c 23, java, python, mysql, and typescript. Problem description given two arrays of strings, words1 and words2, find all strings in words1 that are universal. a string a in words1 is universal if for every string b in words2, b is a subset of a. a string b is a subset of a if every letter in b (with required multiplicity) appears in a. For a word to be a subset of another, every character must appear at least as many times in the target word. the straightforward approach is to check each word in words1 against all words in words2, comparing character frequencies to determine if all words2 words are subsets of words1.
Leetcode 90 Subsets Ii Problem description given two arrays of strings, words1 and words2, find all strings in words1 that are universal. a string a in words1 is universal if for every string b in words2, b is a subset of a. a string b is a subset of a if every letter in b (with required multiplicity) appears in a. For a word to be a subset of another, every character must appear at least as many times in the target word. the straightforward approach is to check each word in words1 against all words in words2, comparing character frequencies to determine if all words2 words are subsets of words1. The word subsets problem can be efficiently solved by reducing the requirements from words2 into a single "maximum letter frequency" profile, and then checking each word in words1 against this profile.

This is part of a series of leetcode solution explanations (index). if you liked this solution or found it useful, please like this post and or upvote my solution post on leetcode's forums. We are given two arrays a and b of words. each word is a string of lowercase letters. now, say that word b is a subset of word a if every letter in b occurs in a, including multiplicity. for example, "wrr" is a subset of "warrior", but is not a subset of "world". now say a word a from a is universal if for every b in b, b is a subset of a.
