最近开始学习数据结构。
一点一点整理，希望能坚持下来。
因为方向是前端，所以用javascript实现。
//sort排序
var testArr1=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
var testArr2=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
var testArr3=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
testArr1.sort();//排序结果：[15, 19, 2, 26, 27, 3, 36, 38, 4, 44, 46, 47, 48, 5, 50]
testArr2.sort(function(a,b){return a>b});//排序结果：[2, 3, 4, 5, 15, 19, 26, 27, 36, 38, 44, 46, 47, 48, 50]
testArr3.sort(function(a,b){return a-b});//排序结果：[2, 3, 4, 5, 15, 19, 26, 27, 36, 38, 44, 46, 47, 48, 50]
//Bubble排序
var testArr1=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
var testArr2=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
function bubbleSort1(array){
for(i=array.length-1;i>0;i--){
for(j=0;j0;i--){
for(j=0;j
//Select排序
var testArr=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
function selectSort(array){
for(i=0;i
//Insert排序
var testArr=[3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48];
function insertSort(array){
for (var i = 0 ; i < array.length-1; i++) {//注意i小于数组的长度-1，否则会造成数组越界，形成死循环
var curElement=array[i+1];
for (var j = i; j >= 0; j--) {
if(curElement
