Minimum Window Substring | Variable Size Sliding Window

[@TheAdityaVerma]

I haven't included the code of this problem in this video and not uploading it right now (although I have it ready): for two reason: 1) Video was getting too long. 2) I want you guys to do it by yourself, since this will be last video in this series and this is the "BAAP" problem of sliding window, if you can do it, I can assure you will be able to do almost any sliding window problem. Try it by yourself, I will upload soon :)

Idea behind iterating Given String length can thought as : 1) Iterate thru string S till the count [map size from String T characters] variable reaches to 0. 2) Once counter is 0, try to move the start pointer towards end pointer to minimize the length of the found substring. If character at start pointer matches with string T increment the count variable. Loop thru till count variable is 0. // String s = "timetopractice"; String t = "toct"; int sLen = s.length(); int tLen = t.length(); if(tLen > sLen) System.out.println("Invalid Input"); HashMap countMap = new HashMap(); for (char c: t.toCharArray() ) { countMap.put(c,countMap.getOrDefault(c,0) + 1); } int start = 0; int end = 0; int maxLen = Integer.MAX_VALUE; int maxStart = 0; // to track Start index of substring int maxEnd = 0; // to track End index of substring int count = countMap.size(); while (end < sLen){ char tempCharEnd = s.charAt(end); if(countMap.containsKey(tempCharEnd)){ countMap.put(tempCharEnd,countMap.get(tempCharEnd) - 1); if(countMap.get(tempCharEnd) == 0){ count--; } } while (count == 0) { if(maxLen > end - start + 1) { maxLen = end - start + 1; maxStart = start; maxEnd = end + 1; } char tempCharStart = s.charAt(start); if (countMap.containsKey(tempCharStart)) { countMap.put(tempCharStart, countMap.get(tempCharStart) + 1); if (countMap.get(tempCharStart) > 0) { count++; } } start++; } end++; } System.out.println(maxLen); System.out.println("Start Index : " + maxStart +" End Index :" + maxEnd + ": "+ s.substring(maxStart,maxEnd));

you don't need maxEnd if you've already found the min lngth i.e. s.substring(maxStart, maxStart + maxLen+1)

[@debangshubanerjee1311]

The condition - if (countMap.get(tempCharStart) > 0) { count++; } is wrong coz here count represents the count of distinct characters, not the count of all characters. It should be -: if (countMap.get(tempCharStart) =1) { count++; }

Input: s = "aaabb", k = 3 Output: 3 Explanation: The longest substring is "aaa", as 'a' is repeated 3 times. Input: s = "ababbc", k = 2 Output: 5 Explanation: The longest substring is "ababb", as 'a' is repeated 2 times and 'b' is repeated 3 times.

C++ Code for the explanation and also made the addition for LC Question as it needs us to return the actual substring : my solution is not the most optimal but this is what i came up with based on my current understanding. string minSubstrWindow(string s, string t) { if(t.length()>s.length()) { return ""; } int res = INT_MAX; // we calc the freq of each char in the map unordered_map map; unordered_map mapS; for(int i=0; i

[@ShivaM-wg9qc]

idea behind returning string as out answer : we use an ans variable since we know we are trying to find the smallest substring we can use that to our advantage and use the minimum window size. So whenever after changing the count to 1 we check if our stored ans length is > then the window if yes than store the string in the window as our answer

Sliding Window Completed 💯..Thank You Aditya Bhaiya 🙏🙏...

[@ashwanisingh8354]

C++ solution along with explanation to few condition I have taken into account string minWindow(string s, string t) { // base case if length of s in smaller than j if(s.size() < t.size()) return ""; // initialize the map to store character ocurring in t along with their count unordered_map map; for (char c : t) map[c]++; // define i and j and n = s.size() along with count int i = 0; int j = 0; int count = map.size(); int n = s.size(); int minSize = INT_MAX; //I am using pair to store the index of smallest resultant substring pair res{-1,-1}; while( j < n){ if(map.find(s[j]) != map.end()){ map[s[j]]--; if(map[s[j]] == 0)count--; } cout
