Mastering Go - Second Edition

Using container/list

This subsection will illustrate the operation of the container/list package using the Go code of conList.go, which will be presented in three parts.

NOTE: The container/list package implements a linked list.

The first part of conList.go contains the following Go code:

package main 
 
import ( 
    "container/list" 
    "fmt" 
    "strconv" 
) 
 
func printList(l *list.List) { 
    for t := l.Back(); t != nil; t = t.Prev() { 
        fmt.Print(t.Value, " ") 
    } 
    fmt.Println() 
 
    for t := l.Front(); t != nil; t = t.Next() { 
    fmt.Print(t.Value, " ") 
    } 
 
    fmt.Println() 
} 

Here, you see a function named printList(), which allows you to print the contents of a list.List variable passed as a pointer. The Go code shows you how to print the elements of list.List starting ...
