Problem
1. Why wouldn't the "or" or "and" function (instead of the "exclusive or" function) work for linear feedback shift registers?
2. Write a program to produce a random two-dimensional image. (Example: generate random bits, write a "*" when 1 is generated, " " when 0 is generated. Another example: use random numbers as coordinates in a two-dimensional cartesion system, write a "*" at addressed points.)
