Can someone tell what’s wrong in this code.
It’s showing wrong answer on submission.
What’s the idea behind function funn ?
There’s no idea behind it
there must be some logic in using these 2 lines, if u would explain it then it would be better for me to find where it went wrong !
First line is combing all odd multiples of power of 2 and second line is connecting that 2^k node to 1st one.
