Design a combinational circuit using logic gates that takes as input a 4-bit binary number, represented via the positions of four switches, and has its outputs control two LEDs as described below.

The LEDs should change according to the following table:

Input Values	Light Setting
	Left LED	Right LED
0-3	On	On
4-7	On	Off
8	Off	On
9	Off	Off
10-11	Off	On
12-15	Off	Off

Your design and implementation process should use the following steps:

Create a truth table for all of the possible inputs and outputs.

Derive a standard Boolean expression from the truth table.

Use K-maps to determine the minimal expression for each of the desired outputs.
