For insertion in the list at the beginning, we created a node t and in its data part, we named it as x. Therefore, if the start is null then start will be put in node t data part and the address part will point to the next part which is NULL. This process will insert the elem...
As the name suggests, this linked list data structure formed a circle. The means all nodes are connected; there is no NULL reference, and it formed a circle. By using a circular linked list, we can start traversing from any node. In a circular linked list, the last node pointer will p...
That is the basic code for traversing a list. The if statement ensures that there is something to begin with (a first node). In the example it will always be so, but if it was changed, it might not be true. If the if statement is true, then it is okay to try and access the n...
The statement, l1.display(); in main( ) invokes display( ) member function, which displays the information part of every node by traversing the linked list starting from the first node to the last node. In-display( ), we have created a pointer of type node which points to the node cur...
A list is a linear collection of data that allows you to efficiently insert and delete elements from any point in the list. Lists can be singly linked and doubly linked. In this article, we will implement a doubly linked list in C++. The full code is her

To find the lowest value we need to traverse the list like in the previous code. But in addition to traversing the list, we must also update the current lowest value when we find a node with a lower value. In the code below, the algorithm to find the lowest value is moved into a ...

Data in all the other nodes are obtained by traversing the linked list starting from the first node referenced by Head. The next attribute of the last node refers to a None object. The next attribute of the last node of a linked list will always refer to the None object. If a linked ...
Both above methods are not practical when the total number of nodes increases in the linked list. If the keys are given in any container, such as an array, vector, or set, we can easily construct a linked list by traversing the container, as shown below:...
