How do you remove the middle from a linked list?

If there are even nodes, then there would be two middle nodes, we need to delete the second middle element. For example, if given linked list is 1->2->3->4->5->6 then it should be modified to 1->2->3->5->6. If the input linked list is NULL, then it should remain NULL.

How do you remove an element from the middle of a linked list in Java?

Traverse through the list till temp points to a middle node. If current not point to null then, delete the middle node(temp) by making current’s next to point to temp’s next. Else, both head and tail will point to node next to temp and delete the middle node by setting the temp to null.

How do you remove an element from the middle of a doubly linked list?

Delete a node in a Doubly Linked List in C++

1. Write struct with data, prev and next pointers.
2. Write a function to insert the node into the doubly linked list.
3. Initialize the doubly linked list with dummy data.
4. Take a node to delete.
5. Write a function to delete the node.

How do you remove the middle of a linked list in Python?

ALGORITHM:

1. Define a Node class which represents a node in the list. It has two properties data and next which will point to the next node.
2. Define another class for creating the circular linked list, and it has two nodes: head and tail.
3. deleteMid() will delete the node from the middle of the list:

How do you remove the middle element from a stack?

Set the default value of the current index variable as 0. Check if the stack is empty or the current index variable is equal to the size of the stack, return. Create a variable x and store the top of the stack in it. Remove/delete the element at the top of the stack.

What’s the best way to delete an element from a doubly linked list?

Algorithm

1. Let the node to be deleted be del.
2. If node to be deleted is head node, then change the head pointer to next current head.

How an element can be deleted from doubly linked list using C program?

Deletion at the end of the doubly linked list

• Copy the last node to a temporary node.
• Shift the last node to the second last position.
• Make the last node’s next pointer as NULL.
• Delete the temporary node.

What is the complexity to delete the middle node in a doubly linked list?

In order to delete a node and connect the previous and the next node together, you need to know their pointers. In a doubly-linked list, both pointers are available in the node that is to be deleted. The time complexity is constant in this case, i.e., O(1).

How do you find the middle element of a linked list in CPP?

Find the middle of a given linked list

1. Method 1: Traverse the whole linked list and count the no. of nodes. Now traverse the list again till count/2 and return the node at count/2.
2. Method 2: Traverse linked list using two pointers. Move one pointer by one and the other pointers by two.
