I was solving this problem 2003D2 - Turtle and a MEX Problem (Hard Version).
I have made two submissions on that Accepted on G++17 278425043, Runtime error on G++20 278423515.
The code on both of the submissions is the same, but i do not know why this code isn't being accepted on G++20.
Even surprisingly when i removed comments from the above submission it is giving TLE verdict.
Accepted on G++17 278459735, TLE on G++20 278459715.
Can anyone explain this strange behaviour?
