Riko is in search of an out-of-print book about eighteenth-century medicine for a school project. what is the best solution if she needs the information immediately?

1. subscribing to a digital classroom
2. logging on to a digital library
3. talking to a doctor through telehealth
4. visiting a digital laboratory

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.
