Got RE in 35th case the python AC submissions for this problem are executed using bfs. I looked at some AC submissions in c++. looks like the logic is same. So the problem I guess is with python.

lets say I avoid recursive implementation and go for iterative ones..for example Bfs over dfs. but is it even possible in all cases? And also if you can provide a feasible way to execute deep recursions without runtime error I will be extremely grateful.

Please don't suggest to learn C++ right now. I know it is a great language. But I just can't afford the time now. I am currently working on learning new skills that will help me in web dev. I hope you understand my position.
