WARNING!

The following blog contains a lot of whining and absolutely useless information. Be cautious, as you may lose your faith in humanity after reading this post. Apologies in advance. TL;DR at the bottom of the entry.

Hello everyone. As a person that extremely enjoys competition, and thus enjoys Codeforces Rounds I really want to adress this issue. Everybody likes hacking other people's solutions and people that GET hacked are either upset about it or are happy (because you know, more room for improvement). But sometimes when people don't hack your solution AND you certainly know that there is a test case that your solution fails at, you quickly look for a bug in code, fix it and re-send it. You see, I got this issue once. But the test case that my solution was failing at was not present in system test cases.

My submissions:

8111607 — Initial Submission

8120543 — Fixed Submission

8244051 — Initial Submission resubmitted after the contest

Guess what? My initial submission passed system tests but couldn't pass my own tests.

Example:

Input:
2
10 15
1
5
Output:
1

However my solution doesn't print out ANYTHING. And yet, it passed system tests. I would understand if it only pretests were that weak (you kno'. to farm hacks) but system tests are not supposed to be that weak.

TL;DR System tests are weak, I'm butthurt and I've been holding in for 3 weeks.
