Pop Operation: Remove WaterMark from Above Flowchartģ. Push Operation: Remove WaterMark from Above FlowchartĢ. Flowchart for Implementing a Stack using Linked List: 1. It consists of nodes where, each node contains a data field and a link to the next node.

You will need to write the code to iterate to position k-1 and switch the pointer, as you said:- eg. currentcurrent.next ' What I mean with 'head' is your 'first'. Linked ListA linked list is a linear data structure, but unlike arrays the elements are not stored at contiguous memory locations, the elements in a linked list are linked to each other using pointers. To delete an entire linked list in java which I have created, Delete elements within a Linked List, Java Program For Writing A Function To Delete A Linked List. We make a recursive call to reverseList with the next node as the new head: let newHead reverseList (head.next) This will recursively reverse the rest of the linked list and return the new head, which in this example is the node with value 5.

isEmpty: It returns true if stack is empty, otherwise false.

Peek or Top: It returns the top element of the stack.

If the stack is empty, then it is said to be in Underflow condition i.e no more items can be deleted. The items are popped out in the reverse order in which they were pushed in.

Pop: It deletes an item from the stack.

If the stack is full, then the stack is said to be in Overflow condition. It can be implemented either by using arrays or linked lists.īasic operations are performed in the stack are: StackStack is a linear data structure which follows LIFO(Last In First Out) or FILO(First In Last Out) order to perform its functions.
