In this homework, you will write a program
to implement a 4-Variable Karnaugh Map simplification process,
and find the minimum sum-of-products expression.
Note that the minimum sum-of-products expression of a function
is not necessarily unique.
You can reference the flowchart on P.132 and implement it in some way
or create an algorithm yourself to simplify your program.
Your program should be compiled as an executable file
(e.g. Sim.exe for win32 environment),
and you can implement your program in any language
(C, C++, and Java, etc.)
Your program should read input.txt, and initial the K-map according to the input file. You cancreate any data structure to allocate the terms of K-Map.
