How would you approach writing a program that clears a grid based on following conditions. 1. Take any grid which has values in each cell. There is a ball that moves in all 8 directions from any point in the grid. 2. The ball starts from any random point on the grid and picks any random direction out of the 8 directions. While moving if it reaches any center of the cell, it will clear the value of that cell. This way we have to clear all the cells. 3. Once the ball reaches the edge, it has to reroute and go in a possible different direction.
