ExamplesAdd node 15 after 10 value node.Approach to solve this problemStep 1 − Define a method that accepts the head of a linked list.Step 2 − If head == nil, return the head.Step 3 − Iterate the given linked list.Step 4 − If temp.value is 10, then add the node 15 as the next node.Step 5 − If node value 10 is not found, return the head without adding any node.Example Live Demopackage main import "fmt" type Node struct {    value int    next *Node } func NewNode(value int, next *Node) *Node{    var n Node    n.value = value ...

ExamplesApproach to solve this problemStep 1 − Let’s define a structure of the node.Step 2 − Make the Linked List such that the previous node would store the address of the next node.Example Live Demopackage main import "fmt" type Node struct {    value int    next *Node } func NewNode(value int) *Node{    var n Node    n.value = value    n.next = nil    return &n } func TraverseLinkedList(head *Node){    fmt.Printf("Linked List: ")    temp := head    for temp != nil {       fmt.Printf("%d ", temp.value)       temp = temp.next    } } ...
