Simple recursion problems python
WebbYou can do loops using recursion and if what need is basically a loop, then a loop is usually the better choice. But recursion is much more than loops. There are plenty of problems which call for recursive solutions and would be incredibly hard to get right without recursion (e.g. recursive descent parsing, mutual recursion). 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.
