listclear
Instructions
Write a function ListClear that deletes all nodes from a linked list l.
- Tip: assign the list's pointer to
nil.
Expected function and structure
func ListClear(l *List) {
}
Usage
Here is a possible program to test your function :
package main
import (
"fmt"
piscine ".."
)
type List = piscine.List
type Node = piscine.NodeL
func PrintList(l *List) {
link := l.Head
for link != nil {
fmt.Print(link.Data, " -> ")
link = link.Next
}
fmt.Println(nil)
}
func main() {
link := &List{}
piscine.ListPushBack(link, "I")
piscine.ListPushBack(link, 1)
piscine.ListPushBack(link, "something")
piscine.ListPushBack(link, 2)
fmt.Println("------list------")
PrintList(link)
piscine.ListClear(link)
fmt.Println("------updated list------")
PrintList(link)
}
And its output :
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
------list------
I -> 1 -> something -> 2 -> <nil>
------updated list------
<nil>
student@ubuntu:~/[[ROOT]]/test$
