Three NOT Gates from Two NOT Gates
Design a 3-input 3-output logic circuit that negates the 3 signals. You have an infinite supply of AND and OR gates but only two NOT gates
I have read and solved many problems like these. Can people post some similar interesting problems using gates. I was asked one such question in my Deutsche Bank Interview which I was not able to answer.
