Why Use a Linked List in Python Full Implementation Linked List in Python Conclusion Python provides us with various built-in data structures. ADVERTISEMENT However, each data structure has its restrictions. Due to this, we need custom data structures. This article will discuss a custom data...
Stacks Operations in Data Structure can be implemented using an array as well as a linked list. The reason that stack is an abstract data structure and adding an element at the head (or top) or linked list can make all the stack operations possible. Stack Operations in Data Structure As w...

Stack<Integer>s=newLinkedStack<Integer>(); The above code completes the stack implementation using linked list but we definitely will be further interested in implementing iterator for the newly createdLinkedStacktype, so that we can iterate through the items currently stored in the data structure....

and then decreasing the top index by one. if it's implemented as a linked list, it involves returning the value of the head node and then moving the head pointer to the next node. in either case, the size of the stack decreases by one. how does the push operation work in a stack?
