Please provide unofficial editorial for WTBTR on May Long '19



Can anyone please provide unofficial editorial of WTBTR since, I don’t know when the official will be released.


Here, you can go through my approach. Its pretty simple to understand and if you have any questions I’ll be happy to answer :smiley:


it is very difficult for me to understand this question, can u please explain any one test case elaborately.


I am soon going to write an editorial :slight_smile:
