find the first node in a linked list in go

To find the first node in a linked list in Go, you need to traverse the linked list from the beginning, which can be done by following the next pointer of each node until NULL is reached. Once you reach the end of the list, the last node's next pointer will be NULL. Here's an example code snippet:

main.go
type Node struct {
    value int
    next *Node
}

func getFirstNode(head *Node) *Node {
    return head
}

In the getFirstNode function, you simply return the head node, which is the first node in the linked list.
