Can't Resolve the runtime error during contest especially in 2.B
By algoacer, history, 12 months ago, In English

I have been stuck in this situation for sometime. Actually I get the logic for solving 2.B in sufficient time but am stuck in one or two pretest. Like for the submission, I am not able to resolve the issue (pretest 5). Please suggest some good practices and how to build logic taking care of corner cases, or writing efficient code.

My submission is: https://codeforces.me/contest/1877/submission/227200089

Please help me taking example for this problem.

one thing that I do is that whenever you are making an integer variable make it a long long because it is always better than realising latter that you should have made a long long after getting a wrong solution verdict

I don't know whether I am qualified to tell you this or not. But to be able to visualize various testcases and its structure is a skill. you just have to use pen and paper to feel the testcase.
