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:

This is really unexpected. Its been nearly 20 days. Next long will start in 6 days, and still we don’t have access to previous long editorials.

Can Anyone find out the test case which my solution is getting wrong…
