ExampleApproachAsk the user to enter the size of array.Make a string array of given size.Ask the user to enter the elements.At the end, print the array.Example Live Demopackage main import (    "fmt" ) func main(){    fmt.Printf("Enter size of your array: ")    var size int    fmt.Scanln(&size)    var arr = make([]string, size)    for i:=0; i

ExampleApproachAsk the user to enter the size of array.Make an integer array of given size.Ask the user to enter elements.At the end, print the array.Example Live Demopackage main import (    "fmt" ) func main(){    fmt.Printf("Enter size of your array: ")    var size int    fmt.Scanln(&size)    var arr = make([]int, size)    for i:=0; i

ExamplesApproachStep 1 − Define a method that accepts the head of a doubly linked list.Step 2 − Initialize temp:=head, count:=0Step 3 − Iterate temp until it becomes nil.Step 4 − Increase count by 1.Step 5 − At the end, print count.Example Live Demopackage main import "fmt" type Node struct {    prev *Node    value int    next *Node } func CreateNewNode(value int) *Node{    var node Node    node.next = nil    node.value = value    node.prev = nil    return &node } func TraverseDoublyLL(head * Node){    // Forward Traversal    fmt.Printf("Doubly Linked List: ")    count := 0 ...
