Using the code below as a starting point, write a program to print the K-map for a 4 variable function. Demonstrate that it works using f(w,x,y,z) = w'x + x'y + y'z + z'w and g(w,x,y,z) = x'y + wx'y'z + z' as examples. Submit the printed source code and the printout of the output of the program for the above function examples. Your program should only print the K-map using the above functions: there is no need for user input.
