Suppose four cars each approach an intersection from four different directions simultaneously. Each corner of the intersection has a stop sign. Assume that traffic regulations require that when two cars approach adjacent stop signs at the same time, the car on the left must yield to the car on the right. Thus, as four cars each drive up to their individual stop signs, each waits (indefinitely) for the car on the left to proceed. Is this anomaly a communication deadlock

A common programming operation is to swap or exchange the values of two vari- ables. If the value of x is currently 19 and the value of y is 42, swapping them will make x into 42 and y into 19. Write a program named swap.py that allows the user to enter two int values. The program should store those values into variables and then swap the variables. Print the values of both variables before and after the swap. You will receive full credit as long as your solution works, but try to do this using as few variables as possible.

Write a program that generates mazes of arbitrary size using the union-find algorithm. A simple algorithm to generate the maze is to start by creating an N x M grid of cells separated by walls on all sides, except for entrance and exit. Then continually choose a wall randomly, and knock it down if the cells are not already connected to each other. If we repeat the process until the starting and ending cells are connected, we have a maze. It is better to continue knocking down the walls until every cell is reachable from every cell as this would generate more false leads in the maze.
