Let's look at how simple it is!
Linked List
A simple linked list.
// Create
let list = DSLinkedList<DSLinkedListNode<Int>>()
// Append
list.append(data: 1)
list.append(node: DSLinkedListNode(data: 2))
// Get
let firstNumber = list[0]
// Remove
list.remove(at: 1)Queue
A simple queue.
// Create
let queue = DSQueue<Int>()
// Enqueue
queue.enqueue(1)
// Dequeue
let firstNumber = queue.dequeue()QuadTree
QuadTree is a special tree data structure. QuadTree is used for spatial decomposition of 2D space. Each node has four subnodes that represent - top left, top right, bottom right and bottom left.
// Create
let treeRootRect = DSQuadRect(origin: .zero, end: CGPoint(x: 100.0, y: 100.0))
let quadTree = DSQuadTree<DSQuadTreeNode<Int>>(rect: treeRootRect)
// Insert
var result = quadTree.insert(node: DSQuadTreeNode(position: CGPoint(x: 10.0, y: 10.0), data: 1))
result = quadTree.insert(node: DSQuadTreeNode(position: CGPoint(x: 12.0, y: 12.0), data: 1))
result = quadTree.insert(node: DSQuadTreeNode(position: CGPoint(x: 70.0, y: 90.0), data: 1))
// Search
let foundNode = quadTree.search(at: CGPoint(x: 10.0, y: 10.0))
let foundNodes = quadTree.search(at: DSCircle(center: CGPoint(x: 50.0, y: 50.0), radius: 25.0))Future
- More data structures. I am only in the beginning.
