insert node at beginning of circular linked list in golang

Go program for insert node at beginning of circular linked list. Here problem description and other solutions.

package main
import "fmt"
// Go Program 
// Insert node at beginning of circular linked list

// Define struct of linked list Node
type LinkNode struct {
	data int
	next * LinkNode
}
func getLinkNode(data int, first * LinkNode) * LinkNode {
	return &LinkNode {data,first}
}
type CircularLinkedList struct {
	head * LinkNode
}
func getCircularLinkedList() * CircularLinkedList {
	return &CircularLinkedList {nil}
}
// Insert node at begining of circular linked list
func(this *CircularLinkedList) insert(value int) {
	// Create a node
	var node * LinkNode = getLinkNode(value, this.head)
	if this.head == nil {
		// First node of linked list
		this.head = node
		node.next = this.head
	} else {
		var temp * LinkNode = this.head
		// Find the last node
		for (temp.next != this.head) {
			// Visit to next node
			temp = temp.next
		}
		// Add node
		temp.next = node
		// make new head node
		this.head = node
	}
}
// Display node element of circular linked list
func(this CircularLinkedList) display() {
	if this.head == nil {
		fmt.Println("Empty Linked List")
	} else {
		fmt.Println("  Linked List Element : ")
		// Get first node
		var temp * LinkNode = this.head
		// iterate linked list
		for (temp != nil) {
			// Display node
			fmt.Print("  ", temp.data)
			// Visit to next node
			temp = temp.next
			if temp == this.head {
				// Stop iteration
				return
			}
		}
	}
}
func main() {
	var task * CircularLinkedList = getCircularLinkedList()
	// Add following linked list nodes
	task.insert(8)
	task.insert(7)
	task.insert(6)
	task.insert(5)
	task.insert(4)
	task.insert(3)
	task.insert(2)
	task.insert(1)
	// Display node
	task.display()
}

Output

  Linked List Element :
  1  2  3  4  5  6  7  8
