Minimum Window Substring - Given two strings s and t of lengths m and n respectively, return the minimum window substring of s such that every character in t (including duplicates) is included in the window. If there is no such substring, return the empty string "".
Mar 4, 2024 · Smallest window in a String containing all characters of other String using Two Pointers and Hashing: The idea is to use the two pointer approach on the hash array of pattern string and then find the minimum window by eliminating characters from the start of the window. Follow the steps below to solve the problem:
Minimum Window Substring in Java. Two strings S1 and S2 are given to us. Our task is to find substring str such that S2 is a subsequence of str. If there are multiple valid substrings, then the substrings of the minimum size should be taken into consideration.
class Solution { public: string minWindow(string s, string t) { vector<int> count(128); int required = t.length(); int bestLeft = -1; int minLength = s.length() + 1; for (const char c : t) ++count[c]; for (int l = 0, r = 0; r < s.length(); ++r) { if (--count[s[r]] >= 0) --required; while (required == 0) { if (r - l + 1 < minLength) { bestLeft = ...
Given strings str1 and str2, find the minimum (contiguous) substring W of str1, so that str2 is a subsequence of W. If there is no such window in str1 that covers all characters in str2, return the empty string "".
Feb 14, 2016 · Description. Given two strings s and t of lengths m and n respectively, return the minimum window substring of s such that every character in t (including duplicates) is included in the window. If there is no such substring, return the empty string "".
Jul 30, 2023 · The Minimum Window Substring is a classical problem that tests one’s understanding of strings, sliding windows, and the ability to write efficient algorithms. We are given two strings, s and t,...
