[20 points] Equipped only with a bucket full of 2-input NAND gates (plus a breadboard, some wires, some SPST switches, an LED, some resistors, and a battery), you must implement the function represented by the ON SET ∑ X,Y,Z (1,6,7) as efficiently and quickly as possible . Show all of your work, plus a complete schematic (including the switches, resistors, LED, and however many 2-input NAND gates deemed necessary)....
