Write a Box class whose init method takes three parameters and uses them to initialize the private length, width and height data members of a Box. It should also have a method named volume that returns the volume of the Box. It should have get methods named get_length, get_width, and get_height.

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.
