I need help problem: A two dimensional random walk simulates the behavior of a particle moving in a grid of points. At each step, the random walker moves north, South, east, or West with probability 1/4, independent of previous moves. Compose a program that takes a command line argument n and estimates how long it will take a random walker to hit the boundary of a 2n-by-2n square centered at the starting point.
