How to add elements to a linked list in Go?

To add elements to a linked list in Go, you can follow the steps below:

Define the structure of a node in the linked list. Each node should contain the value and a pointer to the next node.

type Node struct {
  value int
  next  *Node
}

Create a function to add elements to the linked list. This function will take the current head of the list and the value of the new element as parameters. It will return the updated head of the list.

func addElement(head *Node, value int) *Node {
  newNode := &Node{value: value, next: nil}

  if head == nil {
    return newNode
  }

  current := head
  for current.next != nil {
    current = current.next
  }
  current.next = newNode

  return head
}

Initialize the linked list by assigning the head variable to nil (empty list).

var head *Node = nil

Call the addElement() function to add elements to the linked list.

head = addElement(head, 10)
head = addElement(head, 20)
head = addElement(head, 30)

Now, you have a linked list with elements 10, 20, and 30, and the head variable is pointing to the first node in the list.
