This pull request adds several new Java implementations for singly linked list operations, each in its own file. The main focus is on basic linked list manipulations such as inserting at the head, deleting the last node, searching for an element, and calculating the length of the list. Each file defines its own Node class and demonstrates the respective operation with a sample linked list.

Linked List Operations:

  • Added insertathead.java with a function to insert a new node at the head of a singly linked list, including a demonstration in the main method.
  • Added deletelastnode.java implementing deletion of the tail node from a singly linked list, with sample usage.
  • Added searchinanlinkedlist.java with a function to search for a given value in a singly linked list, returning 1 if found and 0 otherwise.
  • Added lengthodlinkedlist.java providing a function to calculate and print the length of a singly linked list.…length)
