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:...
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...
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...
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 ...
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...
The push_back function takes one argument (the new item element) and inserts it at the end of the list. In this implementation, a pointer to the last node is saved in the list — we will use it to avoid traversing the entire list:void...
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 ...
Algorithm to delete the middle node of a linked listTo solve the problem we follow the following procedure,We initiate the two node pointer name as slow, fast. (like Floyd's tortoise algo, refer the link to my article of merge sort in the linked list). Each time we increment the slow...
Single linked list structure The node in the linked list can be created usingstruct. structnode{// data field, can be of various type, here integerintdata;// pointer to next nodestructnode*next;}; Basic operations on linked list Traversing ...
Algorithm: while we are traversing the list, we mark the head element as mth behind when we arrives at the mth element of the list which is marked as current. As we're looping through, we update both of the marks. So, when the current element reaches the end of the list, we can ...
