Why was the contest deleted. And if so, are there any chances if the contest will return back ??
P.S. - Why did they have to give 6 hours for the problems which were already available on the internet ?? 
That makes some sense.
However such is the working of the codechef you would never know where you went wrong and unnecessarily keep on getting WA or NZEC for problems like this.
BTW source for this problem in geeksForgeeks but they could not structure it properly.
for obvious reasons
because it is codechef
