The bean machine, also known as a quincunx or the Galton
box, is a device for statistics experiments named after English scientist Sir
Francis Galton. It consists of an upright board with evenly spaced nails (or pegs)
in a triangular form, as shown in Figure 7.13.
Balls are dropped from the opening of the board. Every time a ball hits a nail, it has a 50% chance of falling to the left or to the right. The piles of balls are accumulated in the slots at the bottom of the board. Write a program that simulates the bean machine. Your program should prompt the user to enter the number of the balls and the number of the slots in the machine. Simulate the falling of each ball by printing its path. For example, the path for the ball in Figure 7.13b is LLRRLLR and the path for the ball in Figure 7.13c is RLRRLRR. Display the final buildup of the balls in the slots in a histogram. Here is a sample run of the program:
