Hi @vivek_1998299 ,

You can get the editorial for NOV17 challenge problem here: https://discuss.codechef.com/questions/117669/chefnil-editorial

And here you can get a general approach to the challenge problems: https://www.youtube.com/watch?v=cVDYKz9-h-M

Hope this helps!

PS: I could not find any editorial of this, i.e. DEC17 long.
