In this implementation, a stack is manually managed using an array. We use a pointer called top to keep track of the index of the last element inserted into the stack. The stack supports the following ...

Learn the most efficient way to use one array to implement both a stack and a queue, two common data structures for algorithms. See a code example in Java.
