        For a very brief instant I could see the list of problems (but not the statements), and A had 2 ACs.

        That's honestly quite impressive.

        Problemsetting is hard work, it's not fair for problemsetters to have to see hateful comments just because of a technical issue. Every Newton contest that I've seen so far has not had such issues, it's just unfortunate.

    2nd problem

    Problem Statement Consider the integer sequence A = {1, 2, 3, ...., N} i.e. the first N natural numbers in order.

    You are now given two integers, L and S. Determine whether there exists a subarray with length L and sum S after removing at most one element from A.

    A subarray of an array is a non-empty sequence obtained by removing zero or more elements from the front of the array, and zero or more elements from the back of the array. Input The first line contains a single integer T, the number of test cases. T lines follow. Each line describes a single test case and contains three integers: N, L, and S.

    0<N,L<1e9 S<1e18

Does their checker tell the verdict on submitting any code? The server goes down every time I make some submission, not sure if it passed the test cases or not!

    Logic is any S will work as long as it is between sum of first L numbers and sum of last L numbers of {1,2,....,N}

Accordingly to the latest postponement (not announced here) the contest should take place today in less then an hour and it doesn't look like it will. Do you still plan to host it at all, swapnil07?
