Write a method that accepts two 4-bit binary numbers, each in the form of a boolean array. For example, 1011 would be represented by {true, false, true, true}. Your method should use a helper method that emulates the one-bit binary adder using only logic operators. The resulting method may not use any addition, subtraction, multiplication, or division. It must accomplish 4-bit binary adding using only logic operators! The method returns a 5-bit binary number in the form of a boolean array where the most-significant bit (bit 0) represents the final carry bit.
