reverse an array inplace. -4 input AND gate using 2 input AND gates.give 2 ways and compare both.how will you identify which is better if both are given in a black box. -swap elements without using temp,in which case it wont work

Question

Accepted Answer

Questions on array manipulation and logic gates.

To reverse an array inplace, swap the first and last elements and continue swapping towards the middle.
To implement a -4 input AND gate using 2 input AND gates, use two 2-input AND gates and connect their outputs to a third 2-input AND gate.
To compare two black box implementations of an AND gate, test their output for all possible input combinations and compare the results.
To swap elements without using temp, use XOR operation. Example: a = a XOR b, b = a XOR b, a = a XOR b.
Swapping elements without temp won't work if both elements are the same (e.g. a = a XOR a).
