# LinkedList 

Stable and mutable singly and doubly linked lists in Motoko

## Motivation

**Careful, these operations mutate the underlying linked lists involved!**

Sometimes you want both an efficient prepend and append, and the fact that your underlying data structure is mutating just isn't as important as the consistent performance of operations on that data.

## API Documentation

API documentation for this library can be found at https://canscale.github.io/LinkedList

## Usage

Install vessel and ensure this is included in your package-set.dhall and vessel.dhall

Singly Linked List Example

```

import LL "mo:linkedlist/LinkedList";

import Nat "mo:base/Nat";

...

// create, append, and prepend to a linked list

var l1 = LL.empty();

l1 := LL.append(l1, 5); 

l1 := LL.prepend(l1, 3); 

// merge two linked lists

var l2 = LL.empty();

l2 := LL.append(l2, 8); 

l2 := LL.append(l2, 10); 

// Careful! This mutates both l1 and l2

let l3 = LL.merge(l1, l2);

```

```

import DLL "mo:linkedlist/DoublyLinkedList";

import Nat "mo:base/Nat";

...

// create, append, and prepend to a doubly linked list

var l1 = DLL.empty();

l1 := DLL.append(l1, 5); 

l1 := DLL.prepend(l1, 3); 

// merge two doubly linked lists

var l2 = DLL.empty();

l2 := DLL.append(l2, 8); 

l2 := DLL.append(l2, 10); 

// Careful! This mutates both l1 and l2

let l3 = DLL.merge(l1, l2);

// pop elements from the head and tail of a doubly linked list

let (l4, poppedHead) = DLL.popHead(l3); 

let (l5, poppedTail) = DLL.popTail(l3); 

```
