Following is my code to the problem [Link](https://codeforces.com/contest/777/problem/C)↵

I=lambda:[*map(int,input().split())]↵

↵
It gives TLE in some submissions while passes in others, to the fact that all have same code.↵
Also sometimes for the same code Python 3 throws TLE and sometimes PyPy3. ↵
Is there any way to overcome this uncertainty,↵
Or can anyone pls give reason for this↵
