7. Assume the scenario is reversed: You need to evaluate Boolean circuits, but you have a program that evaluates Boolean formulas. Analogously to the previous problem, it is easy to evaluate Boolean circuits directly in linear time. The spirit of this problem is to avoid doing so! (a) Assume that you are allowed to use the program that evaluates Boolean formulas only once. Briefly explain how you would use the Boolean formula evaluation program to evaluate a Boolean circuit. Show what you would do on the circuit in Part 4b. Make sure to state the formula that is input to the program that evaluates Boolean formulas. output Tooo
