I always saw Python(CPython) as inferior to PyPy3, because of **SPEED** ↵
↵
but today while working on a easy problem([problem:189A]) I found that I was getting repeated _Runtime Errors_. I tried to improve my code but my solution didn't got Accepted.↵

My (Runtime error) PyPy3 solution:↵

↵
after struggling for sometime, I thought I should give Python(CPython3) a try and submitted the same code in Python3. Voila!! I got AC immediately.↵
↵
My (Accepted) Python3 solution:↵

↵
What was I doing wrong? I don't know clearly for now, but I can see that there is a huge difference in memory consumption of Python3(8952 KB) and PyPy3(24604 KB). Maybe my solution was taking too much memory in PyPy3 and that's why it got Runtime error.↵
↵
I googled about it for few minutes and found a wonderful article explaining why PyPy3 consumes lot of memory:↵

↵
This article basically says: The main reason why PyPy is faster than CPython is that PyPy delays garbage collection. Please correct me if I am wrong.↵
↵
I will try to replicate this in my local system and see what's happening. If get any new info, then I will add it here.↵

TLDR;UseTry Python when you are getting error with PyPy↵
