Just started using Codeforces. Wrote solution for this problem: (231A Team)https://codeforces.com/problemset/problem/231/A It gave me execution time 218ms in Python 3. I was curious how others made it 46ms when my solution is not that much different. So, to test I copied and pasted the best solution written in Python3 and I still got 218ms when they got 46ms. Why is this happening? Is this difference in execution time (in)significant? Thank you.
