Problem Set

There are five exercises in the problem set; you will be creating a file for each program. Please name your files prog1.1
These five files should end up in a subdirectory of your home directory, called lab1.
  1. With Frodo in the initial position shown below, simulate the execution of the following program. Frodo's task is to find the ring, pick it up, and then turn himself off. Use the map below to determine the final situation and state whether an error occurs. If an execution or intent error does occur, rewrite the program to correct the problem.
    frodo -m map1.1
