One of the things you’ll learn a lot about if you pursue any sort of formal education in computing science is data structures. However, once I hit the real world then it seemed like for most problems the speed differential between a linked list and a System.Collections.Generic.List wasn’...
Whenever an element is added in the stack, it is added on the top of the stack, and the element can be deleted only from the stack. In other words, a stack can be defined as a container in which insertion and deletion can be done from the one end known as the top of the stack....
Insertion in-between nodes Insertion at the end Suppose we have a circular linked list with elements 1, 2, and 3. Initial circular linked list Let's add a node with value 6 at different positions of the circular linked list we made above. The first step is to create a new node. all...
We have only covered three basic linked list operations above: traversal (or search), node deletion, and node insertion. There are a lot of other operations that could be done with linked lists, like sorting for example. Previously in the tutorial we have covered many sorting algorithms, and...

It can be seen that if the sequence table is very long, if the insertion efficiency is relatively low in the first place (the insertion time complexity is O(n)), if the insertion is frequent, the complexity is quite high. Delete operation ...

get(index) : Get the value of theindex-th node in the linked list. If the index is invalid, return-1. addAtHead(val) : Add a node of valuevalbefore the first element of the linked list. After the insertion, the new node will be the first node of the linked list. ...
The next two sections look at the technical approach in detail and demonstrate how and why the indirect addressing approach is so neat. The last section extends the solution from item deletion to insertion. The code The basic data structure for a singly linked list of integers is shown in Fig...
