#Install $npm install javascript-algorithms

##Binary Search Tree

var bst = new js_algorithms.BinarySearchTree();

bst.insert({x: 4}, function (a, b) {
  return a.x > b.x;//if you want add less value to left brench, use '>' operator,
});

bst.getMax();

bst.getMin();

bst.find(23, function (a) {
  return a.x;
});

bst.remove(function(a){
  return a.x == 23;
});

##Doubly Linked List

var list = new js_algorithms.DoublyLinkedList();

list.insert({name:"omer",surname:"demircan"});

list.find(function(a){
  return a.name == "omer";
});

list.remove(function(a){
  return a.surname == "çevik";
});

##Hash

var hash = new js_algorithms.Hash({size: 137});

hash.put({name: "omer"});

hash.get({name: "omer"})

##Linked List

var llist = new js_algorithms.LinkedList();

llist.insert({name: "omer"});

llist.find(function(a){
  return a.name == "omer";
});

llist.remove(function(a){
  return a.name == "pamir";
});

##Graphs

var g = new js_algorithms.Graph(GRAPH_SIZE);

g.addEdge("a", "b", 3);
g.addEdge("a", "c", 5);
g.addEdge("b", "e", 1);

var p = g.dijkstra("a","e"); //Output : [a,b,e]

g.clearVisitedList();
var g.depthFirstSearch(START_NODE);

g.clearVisitedList();//clear before visited list (set to false all of them)
var g.breadthFirstSearch(START_NODE);

##Sort Algorithms

var s = new js_algorithms.Sorting();

//select any arr variable
var arr = s.CreateRandomArray(11).data; //[,4,6,7,3,66,3]
var arr = [{x:4,y:6},{x:2,y:7},{x:66,y:3},{x:14,y:0},{x:6,y:5},{x:2,y:5}];

s.selectionSorting(arr, function(a, b){
  return a.x < b.x;
});

s.insertionSort(arr, function(a, b){
  return a.x < b.x;
});

s.shellSort(arr, function(a, b){
  return a.x < b.x;
});

//only mergeSort callback is different from other 
s.mergeSort(arr, function(a){
  return a.x;
});

s.quickSort(arr, function(a, b){
  return a.x < b.x
});

##Huffman

var huffman = new js_algorithms.Huffman("omer demircan");
huffman.encode();//returned : 1011101100...
