In the Exploration problem, a robot is placed at the center of an 11 meter long line. Each “second”, the robot takes a 1 meter step either Left or Right at random.

a) Write a program to determine how long the robot will walk before reaching either end of the line. Have the program average Nth trials, and report the average and longest time. Final presentation of your result after Nth trials is expected to be part of your program, properly formatted.

b) Your program to show the position of the robot after each step:

c) Determine if there is any relationship between which end of the line the robot reaches and the
length of the walk. “Your Robot has a tendency to go to the with an average of ”. Print the average and longest walks for each end of the line.
