Hello Everyone! Today I encountered a weird bug for the first time. So basically I was submitting some code to a problem and that's when I encountered this weird bug where I got wrong answer on test case 1 even though when I copied the input and tried it in my code editor it passed the first testcase? Can anyone see why this happened pls. Thank you. Here's the problem and the submission: [problem:https://codeforces.me/problemset/problem/2191/B] and [submission:https://codeforces.me/contest/2191/submission/368125504].

I mean it has been nearly 3 months since the last div 4. It it taking too long. While other div 1, div 2, div 3 happen way more often? Like for me it doesn't matter, because I depend on div 3's and div 2's sometimes. I understand that div 1, div 2, div 3 will always be more often, but why did the next div 4 take so much time? I really appreciate the help!
