I had int n,i; and I had wa #10, then I changed them to long long and got ac, but I can't understand why I got wa10 with int n,i; where i and n can't exceed 10^6.

Same thing :(

Re: for wa#10

It's obviously a mistake in task's text. Program won't be accepted until it will work with n=10e6.

thanks for your hint, helped me to get accepted verdict

Re: for wa#10

When you divide at the end by n*(n - 1) it gets overflow so you need to have type long long

Re: for wa#10

You need long long n.

Because you divide at the end by n*(n - 1),n*(n-1) is overflow.
