I was working on today's contest, Codeforces Round 933 (Div. 3). On problem F, I had gotten a Runtime Error. I spent over an hour debugging it, and finally did, but wasted a lot of time. It turned out my issue was having an empty set and doing operations on it. skul
Is there any way to quickly find where is your Runtime Error in your code? I have gotten Runtime Error multiple times, and debugging is always the most annoying part. skul
Thanks!
