A naïve solution for the above-stated problem is to evaluate all of the possible combinations of different pieces of varying size to find the maximum revenue-generating combination. Although this method seems the easiest and quick to practice, it has exponential time complexity. So there is a need to figure out a better method than this.

---SIMPLIFICATION VIA BOOLEAN ALGEBRA--- 1.) Use boolean algebra to simplify the equation. SHOW YOUR WORK, one step per line. You should use only variable names, negation (with ``), AND (by putting terms next to each other), OR (with `+`), and parentheses. In addition, each line should start with an equal sign (`=`). The first step has been done for you to show how. As a hint, problem 1c requires De Morgan's Law. Example) f(Z,Y,X) = (!Z+Z)Y!X + !YX = Y!X + !YX = !ZY!X + ZY!X + !YX la) f(A,B,C) = !A!BC + A!B!C + !ABC + !AB!C + A!BC
