sometimes I use python3 over PyPy3 and I get better performance specially on the memory usage

255135410-->Python3 — time: 140 ms — Memory: 6600 KB 255135440--> PyPy3 — time: 156 ms — Memory:19196 KB problem[problem:B. Rebellion]

the same code for both solutions

How to know when to submit with Python3 over PyPy?

thanks in advance
