Webb20 sep. 2024 · Recursion, along with it, also brings some of its own disadvantages. Some are : It is slower as compared to iteration. Logical but difficult to find the error, if any exists. Requires extra storage space this is because, for every recursive call, separate memory is allocated for the variables. WebbThe idea for the solution: Recursion and Backtracking We can describe the idea for the solution as follows: Represent the maze as a bidimensional array (or a list of lists). Define one character to state that the room is empty and another for rooms that someone cannot go through. There are four possible moves: forwards, backwards, left and right.
