Nice video bro

I subscribed ,good !on new year day u doing coding , no one can stop you ! Keep it up !!

Nice explanation

import java.util.*; class telugu{ public static int Replacement(String s,int k){ HashMap<Character,Integer> hm =new HashMap<>(); int l=0; int maxF=0; int maxL=0; for(int r=0;r<s.length();r++){ char ch=s.charAt(r); hm.put(ch,hm.getOrDefault(ch, 0)+1); maxF=Math.max(hm.get(ch),maxF); if(r-l+1-maxF<=k){ maxL=r-l+1; }else{ while((r-l+1)-maxF>k){ char ch1 =s.charAt(l); hm.put(ch1,hm.getOrDefault(ch1,0)-1); if(hm.get(ch1)==0){ hm.remove(ch1); } l++; } } } return maxL; } public static void main(String[] args){ String s="ABAA"; int k=0; System.out.println(Replacement(s, k)); } } solution in java

Wonderful explanation the way you are explaining 😎🤏 fantastic keep going

Do not stop this series

Excellent explanation❤❤❤

anna miru different approaches vadthunnaru and vatiki code kuda chupinchi oka 1 min explanation isthe chala bavuntadhi and useful untdhi anna.

broo order to patu bytes lo kuda cheppandiii

Thankyou for the content, looks amazing. Is it possible to share java example of model-2 approach (moving of first and last pointers to right by cleverly eliminating elements)?

Brute Force : int main() { string s; cin>>s; int k; cin>>k; int n = s.size(); int Max = 0; for(int i=0;i<n;i++) { unordered_map<int,int>m; int Maxfreq = 0; for(int j=i;j<n;j++) { m[s[j]]++; Maxfreq = max(Maxfreq,m[s[j]]); if(((j-i+1)-Maxfreq)>k) { break; } Max = max(Max,(j-i+1)); } } cout<<Max; } Time Complexcity : O(n^2) Optimized Code : int characterReplacement(string s, int k) { int n = s.size(); int Max = 0; unordered_map<int,int>m; int l=0; int r=0; int Maxfreq=0; while(r<n) { m[s[r]]++; Maxfreq = max(Maxfreq,m[s[r]]); while(((r-l+1)-Maxfreq)>k) { m[s[l]]--; Maxfreq = max(Maxfreq,m[s[l]]); l++; } Max = max(Max,(r-l+1)); r++; } return Max; } Time Complexcity : O(n)

speechlesss ,one of the best explanations in youtube. please continue the theory like this ,it gives confidence
