How would you find the last element in a linked list?

## How would you find the last element in a linked list?

getLast() method is used to fetch or retrieve the last element from a LinkedList or the element present at the tail of the list.

## How will you find the nth number from last in a single linked list?

Algorithm to find the Nth node from the end (using the length of the linked list)

1. Input the number of nodes of the linked list.
2. Input all the nodes and create the linked list.
3. Input the Nth node to be returned from the end of the linked list.
4. Find the length of the linked list.
5. Return (length – N + 1)th node.

How do you find the k th node from the last in a linked list?

The idea is to start from the head node and move a pointer k nodes ahead in the given list. Then, take another pointer starting from the head node and run both pointers in parallel till the first pointer reaches the end of the list. Now, the second pointer will point to the k’th node from the end.

What does the last item in a linked list point to?

The first and last node of a linked list usually are called the head and tail of the list, respectively. Thus, we can traverse the list starting at the head and ending at the tail. The tail node is a special node, where the next pointer is always pointing or linking to a null reference, indicating the end of the list.

### How do you find the last element in a linked list in Python?

Program to find the K-th last node of a linked list in Python

1. klast := node.
2. last := node.
3. for i in range 0 to k, do. last := next of last.
4. while next of last is not null, do. last := next of last. klast := next of klast.
5. return value of klast.

### How do you find the third last element of a linked list?

1. Use two pointers: pointer-1 and pointer-2.
2. make pointer-1 points to third node in single linked list.
3. Now set pointer-2 points to first-node pointer-2 = node1; // point to 1st nd node1–>node2–>node3–>node4—> ……

How do you find the third node from the end in a singly linked list in C?

Program for n’th node from the end of a Linked List in C program

1. Take a temporary pointer, let’s say, temp of type node.
2. Set this temp pointer to first node which is pointed by head pointer.
3. Set counter to the number of nodes in a list.
4. Move temp to temp → next till count-n.
5. Display temp → data.

How do I find the last node in a linked list Python?

## Should print the Nth node from the end of the linked list?

Given with n nodes the task is to print the nth node from the end of a linked list. The program must not change the order of nodes in a list instead it should only print the nth node from the last of a linked list.
