(c) Four friends A, B, C and D want to decide if they want to go to a movie or watch a football game. They each cast their vote by writing "0" or "1" on a piece of paper. If the number obtained by adding their votes is an even number, they will go for a movie and vice versa. Design a circuit with input as the 4 votes and output as the decision to go for a movie. You can only use 1-bit Full-adders and NOT gates to produce your final circuit. Try to minimize the number of components.
