Go/Lists
From charlesreid1
To use lists in Go, use the "container/lists" package. This will import a linked list object. import "container/list"
Link: https://golang.org/pkg/container/list/
Examples
Basic Example
in the following basic example, we create a new list, populate it, and iterate over it with a for loop to print out its elements:
package main import ( "fmt" "container/list" ) func main() { // Initialize list l := list.New() // Populate list e4 := l.PushBack(4) e1 := l.PushFront(1) // State of list is [1, 4] l.InsertBefore(3, e4) l.InsertAfter(2, e1) // State of list is [1, 2, 3, 4] // Iterate over list for e := l.Front(); e != nil; e = e.Next() { fmt.Println(e.Value) } }
Useful Built-In List Methods
There are several built-in methods for lists (see full list here: https://golang.org/pkg/container/list/). These include:
- Back()
- Front()
- Init()
- Len()
- PushBack()
- PushFront()
If we are iterating over a list and are using Front() and Back() to get references to specific elements, the list element objects also have two built-in methods:
- Next()
- Prev()
These methods are available via the element object itself and yield new element objects.
