Dr. Tawanda Mushiri is a Senior Research and Lecturer as well as a Robotics, AI and Health 4.0 expert. Like DFS, online DFS is incomplete for reversible state spaces This implementation does the same as yours for "square" lists of lists: A list can be copied by slicing the whole list with [:], and you can use a list comprehension to do this for every row. This combines the speed of C++ with the convenience of Python. There are many problems in online coding contests which involve finding a minimum-cost path in a grid, finding the number of ways to reach a particular position from a given starting point in a 2-D grid and so on.
