Leetcode Solutions 5781. Remove All Occurrences of a Substring

[@SaurabhJeena-sh4gh]

class Solution { public String removeOccurrences(String s, String part) { StringBuilder str=new StringBuilder(); for(int i=0;i=0&&str.substring(j).equals(part)){ str.setLength(j); } } return str.toString(); } } runs in 5 ms time done by myself had a great boost in confidence ..code is small but it took me 6 hours to come up to this solution

It was very helpful sir!!,I was able to solve 3 questions during yesterdays contest so am i somewhat at good level sir? Suggest me some ideas so that i can consistently solve 3-4 questions on leetcode contests

[@mohammadfraz]

You are doing good. Keep practicing

[@agree.]

Was waiting for it

[@mohammadfraz]

Thanks 😊

[@rajgupta5158]

3rd question is based on dp in which I not so good, Sir can you provide some tips to me to do at least 3 questions because I got a stack to solve only 2 problems in each contest except very few contest this thing very demotivated for me.

[@mohammadfraz]

I told everything in video bro , I provided resources also

[@sahilbhaiya6200]

Helpful video 👍

[@mohammadfraz]

Thanks

@@mohammadfraz it's my pleasure 👍

[@abhishekvishwakarma9045]

Have you done Competitive programing just want some reviews on that

[@mohammadfraz]

Yes I have

[@Code_Note]

Bhaiya I had this question in mind why doesn't leetcode gives the access to see the submissions of others because many a times we write buggy codes which somehow sometimes passes test cases (generally weak test cases).So if we can access the submissions of top in ranklist then we can debug our code as well and stress testing to find such cases.

[@mohammadfraz]

No they don't allow access to other's cases

string removeOccurrences(string s, string part) { while(s.find(part)!=-1){ s.erase(s.find(part),part.size()); } return s; }

@@mohammadfraz yes bhaiya it was, but now they have changed. Thank you for replying, you are doing a great work for CS Community. 🙏 Just one suggestion, is that, please make the video solution more comprehensive, so that beginners can also take advantage of your videos. ☺
