Question

Bookdiscusses two implementations of stacks in detail: Array (stackType- pages 410-420) and Linked List (linkedStackType - pages 428-439).Review their definitions and methods closely. Identify theoperations for which time complexities differ between twoimplementations.

initializeStack
destroyStack

isEmptyStack

isFullStack

push

top

pop

Explanation / Answer

In array stack initialization take O(n) time and inlink list case it will be O(n2) time. in destory stack both will also take equal time=O(n)time is empty Stack is constant time operation in both cases. isfull stack is available in array, in linklist if thememory is available then you can add more elements and stack willnever full. push is costly in linklist. and will take O(n2) time to movethe elements backward and add in front of the list. In array it isO(n) operation just add the element at the end of array.. top is constant time operation for both cases. PoP is also a constant time opertion in both cases.
