Question
In an array implementation of a stack, we can include code that will automatically allocate more memory if every element of the array is occupied. Which stack operation should invoke this code? A. push B. pop C. peek D. poke E. none of the above
Solution 1
The stack operation that should invoke this code is A. push. This is because the push operation is used to add an element to the stack. If every element of the array is occupied, we would need to allocate more memory to add (or push) a new element onto the stack.
Solution 2
The stack operation that should invoke this code is A. push. This is because when we try to add (or "push") a new element onto the stack and find that there is no more space, that's when we would need to allocate more memory to accommodate the new element.
