&/p&&p&研一做了一年项目之后，感觉自己解决问题的能力、快速上手新技术的能力有所提升，但做项目一味求快、一味赶时间，我对很多技术的理解仅停留表面。所以更多时候我感觉自己是在搬砖，很难写出高质量的代码。当时我决定，研二的上半学期一定要好好稳固基础，深入理解技术背后的原理，放慢做项目的节奏，不一味地盲目求快。 &/p&&p&然而研二因为种种原因，我去了一家创业公司实习。既然我无法选择，那我就拥抱变化。既来之则安之，我希望自己所花的时间都有所收获。所以我全身心投入到工作中去。公司安排我做前端，虽然这并不是我想干的事情，但当前别无选择，既然做那就得做好。我花了一个月的时间怒刷前端知识，学习Angular、React，了解它们的设计思想，学习JS背后的原理，也看到了前端目前的发展状况。前端的技术迭代速度很快，但技术背后的原理都是类似的，所以抓住技术背后的本质才是最重要的。&br&&/p&&p&这段实习一直持续到了今年一月，我心理清楚，二月底三月初阿里的实习招聘就要开始，所以我挤出中午休息时间、晚上下班后的时间、周末的时间，复习我之前积累的东西。
&/p&&p& 三月三号，人生的第一次面试，在看到杭州的电话时，那一刻的心情既忐忑又兴奋。在此之前，我并不清楚自己的水平在所有应届生中处于一个怎样的层次，在电话接通之前我已经做好了充分的心理准备，想象了各种被面试官吊打的画面。第一次面试持续了54分钟，面试官似乎破有耐心，整个面试过程相谈甚欢。那一次的面试给了我巨大的信心，因为我清楚，我离我的目标更近了一步。
&/p&&p&在接下来的一个月中，我陆陆续续接到了五次面试电话，每一次面试都是一次学习的机会，能发现自己的不足，在与面试官交流的过程中也能了解到最新的技术、最佳的实现方法。
&/p&&p&四月十四，记得那天刚替导师给本科生上完算法课，晚饭过后便收到的阿里的offer。当时的喜悦之情溢于言表，这么久的努力没有白费。但我心里也清楚，阿里的实习转正率向来很低，要想通过实习留下来也不是一件容易的事。所以在收到阿里offer之后的那晚，我重新规划了接下来的学习计划，将我的短期目标更新成：拿下阿里转正offer。 &/p&&p&&br&&/p&&p&5.20，一个美好的日子，我怀着憧憬、忐忑、兴奋的心情走进了支付宝大楼，开始了我三个月的实习生涯。这三个月的实习让我学到了很多，我看到了每天的进步，也看到了自己的不足。这100天经历了太多的事情，有太多的体会，有空我再单独写一篇实习期间的感悟与大家分享。 &/p&&p&9.1晚上11点，我的状态从『面试中』变成了『待跟进offer』，我会心一笑，我达成了人生第一阶段的目标。那一刻我没有太多的激动，在经过了2017年8个月的持久作战之后，这个offer早已在我的意料之中。 &/p&&p&第二天是周六，这个周末我给自己放了两天的假。虽然在杭州已经呆了102天，虽然支付宝大楼就在西湖边，但每天两点一线的工作，我并没有去过西湖。那一晚我的基友（帅气的天哥，文末附有征婚启示）得知我收到offer后便立即买票，坐了一夜的火车来杭州为我庆祝。也托他的福，在这个周末我第一次游览了这座美丽的城市。 &/p&&p&&br&&/p&&p&最后的校园时光，我给自己定了一个新的目标，这个目标也许充满了挑战、充满了艰辛与困难，但我想如果能达成，我的人生将会有很大的改变。在人生的路上，我还在奋斗。希望与各位共勉。 &/p&&hr&&h2&&b& 一些建议&/b& &/h2&&p&&b& 建议1：养成写博客的习惯 &/b&&/p&&p&在面试阿里的过程中，博客帮了我很大的忙。并不是说有博客在面试中会加分，而是写博客的过程能加深你对知识的理解，而且回顾起来也特别高效（毕竟是自己写的东西）。 &/p&&p&我从研一开始便养成了写博客的习惯，现在先过头来，这两年我一共写了185篇文章，有22W的访问量，也很荣幸称为专家博主。我的博客现在已经成为我一笔最宝贵的财富，记录了我技术的整个体系结构，也记录了学习技术的心路历程。 &/p&&p&可能很多同学都有写博客的经历，但能长期坚持的少之又少。我想告诉大家，任何事情都贵在坚持。只要坚持21天就能养成习惯。有的时候对这件事缺乏兴趣了很难再持续下去，但想想自己的目标，咬咬牙坚持下去，养成习惯你就赢了。 &/p&&p&我的博客一般都是看完一本书后的总结，我会把一本书中最核心的东西，按照我的理解把它们记录下来。每一本书我都会看三遍，第一遍是快速浏览，了解整本书的体系结构、作者的行文思路，知道书中重要的、不重要的内容，也就是要建立起全局观。第二遍我会精读，把那些我认为重要的内容挑选出来着重阅读、反复理解、吃透。第三遍阅读，往往会冒出新的理解，我时常有这种『书读百遍，其义自见』的感觉。三遍读完后，我便按照自己的理解，把核心内容写成博客。由于是自己的写的东西，所以在复习的时候只要花上三五分钟通读一遍，所有的知识点又被唤醒。 &/p&&h2&建议2：未完待续…… &/h2&&hr&&h2& Java体系结构整理 &/h2&&ul&&li&

int length=a.//数组长度，将这个提取出来是为了提高速度。
int insertN//要插入的数
for(int i=1;i&i++){//插入的次数
insertNum=a[i];//要插入的数
int j=i-1;//已经排序好的序列元素个数
while(j&=0&&a[j]&insertNum){//序列从后到前循环，将大于insertNum的数向后移动一格
a[j+1]=a[j];//元素移动一格
a[j+1]=insertN//将需要插入的数放在要插入的位置。
&/code&&/pre&&/div&&h1&2.希尔排序&/h1&&blockquote&&p&对于直接插入排序问题，数据量巨大时。&/p&&/blockquote&&ol&&li&将数的个数设为n，取奇数k=n/2，将下标差值为k的书分为一组，构成有序序列。&/li&&li&再取k=k/2 ，将下标差值为k的书分为一组，构成有序序列。&/li&&li&重复第二步，直到k=1执行简单插入排序。&/li&&/ol&&br&&p&如何写成代码：&/p&&ol&&li&首先确定分的组数。&/li&&li&然后对组中元素进行插入排序。&/li&&li&然后将length/2，重复1,2步，直到length=0为止。&/li&&/ol&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&public
void sheelSort(int[] a){
while (d!=0) {
for (int x = 0; x & x++) {//分的组数
for (int i = x + i & a. i += d) {//组中的元素，从第二个数开始
int j = i -//j为有序序列最后一位的位数
int temp = a[i];//要插入的元素
for (; j &= 0 && temp & a[j]; j -= d) {//从后往前遍历。
a[j + d] = a[j];//向后移动d位
a[j + d] =
&/code&&/pre&&/div&&h1&3.简单选择排序&/h1&&blockquote&&p&常用于取序列中最大最小的几个数时。&/p&&/blockquote&&p&(如果每次比较都交换，那么就是交换排序；如果每次比较完一个循环再交换，就是简单选择排序。)&/p&&ol&&li&遍历整个序列，将最小的数放在最前面。&/li&&li&遍历剩下的序列，将最小的数放在最前面。&/li&&li&重复第二步，直到只剩下一个数。&/li&&/ol&&br&&p&如何写成代码：&/p&&ol&&li&首先确定循环次数，并且记住当前数字和当前位置。&/li&&li&将当前位置后面所有的数与当前数字进行对比，小数赋值给key，并记住小数的位置。&/li&&li&比对完成后，将最小的值与第一个数的值交换。&/li&&li&重复2、3步。&/li&&/ol&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&
public void selectSort(int[] a) {
int length = a.
for (int i = 0; i & i++) {//循环次数
int key = a[i];
int position=i;
for (int j = i + 1; j & j++) {//选出最小的值和位置
if (a[j] & key) {
key = a[j];
position =
a[position]=a[i];//交换位置
&/code&&/pre&&/div&&h1&4.堆排序&/h1&&blockquote&&p&对简单选择排序的优化。&/p&&/blockquote&&ol&&li&将序列构建成大顶堆。&/li&&li&将根节点与最后一个节点交换，然后断开最后一个节点。&/li&&li&重复第一、二步，直到所有节点断开。&/li&&/ol&&br&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&public
void heapSort(int[] a){
System.out.println(&开始排序&);
int arrayLength=a.
//循环建堆
for(int i=0;i&arrayLength-1;i++){
buildMaxHeap(a,arrayLength-1-i);
//交换堆顶和最后一个元素
swap(a,0,arrayLength-1-i);
System.out.println(Arrays.toString(a));
void swap(int[] data, int i, int j) {
// TODO Auto-generated method stub
int tmp=data[i];
data[i]=data[j];
//对data数组从0到lastIndex建大顶堆
private void buildMaxHeap(int[] data, int lastIndex) {
// TODO Auto-generated method stub
//从lastIndex处节点（最后一个节点）的父节点开始
for(int i=(lastIndex-1)/2;i&=0;i--){
//k保存正在判断的节点
//如果当前k节点的子节点存在
while(k*2+1&=lastIndex){
//k节点的左子节点的索引
int biggerIndex=2*k+1;
//如果biggerIndex小于lastIndex，即biggerIndex+1代表的k节点的右子节点存在
if(biggerIndex&lastIndex){
//若果右子节点的值较大
if(data[biggerIndex]&data[biggerIndex+1]){
//biggerIndex总是记录较大子节点的索引
biggerIndex++;
//如果k节点的值小于其较大的子节点的值
if(data[k]&data[biggerIndex]){
//交换他们
swap(data,k,biggerIndex);
//将biggerIndex赋予k，开始while循环的下一次循环，重新保证k节点的值大于其左右子节点的值
&/code&&/pre&&/div&&h1&5.冒泡排序&/h1&&blockquote&&p&一般不用。&/p&&/blockquote&&ol&&li&将序列中所有元素两两比较，将最大的放在最后面。&/li&&li&将剩余序列中所有元素两两比较，将最大的放在最后面。&/li&&li&重复第二步，直到只剩下一个数。&/li&&/ol&&br&&p&如何写成代码：&/p&&ol&&li&设置循环次数。&/li&&li&设置开始比较的位数，和结束的位数。&/li&&li&两两比较，将最小的放到前面去。&/li&&li&重复2、3步，直到循环次数完毕。&/li&&/ol&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&public void bubbleSort(int[] a){
int length=a.
for(int i=0;i&a.i++){
for(int j=0;j&a.length-i-1;j++){
if(a[j]&a[j+1]){
temp=a[j];
a[j]=a[j+1];
&/code&&/pre&&/div&&h1&6.快速排序&/h1&&blockquote&&p&要求时间最快时。&/p&&/blockquote&&ol&&li&选择第一个数为p，小于p的数放在左边，大于p的数放在右边。&/li&&li&递归的将p左边和右边的数都按照第一步进行，直到不能递归。&/li&&/ol&&br&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&public static void quickSort(int[] numbers, int start, int end) {
if (start & end) {
int base = numbers[start]; // 选定的基准值（第一个数值作为基准值）
// 记录临时中间值
int i = start, j =
while ((numbers[i] & base) && (i & end))
while ((numbers[j] & base) && (j & start))
if (i &= j) {
temp = numbers[i];
numbers[i] = numbers[j];
numbers[j] =
} while (i &= j);
if (start & j)
quickSort(numbers, start, j);
if (end & i)
quickSort(numbers, i, end);
&/code&&/pre&&/div&&h1&7.归并排序&/h1&&blockquote&&p&速度仅次于快排，内存少的时候使用，可以进行并行计算的时候使用。&/p&&/blockquote&&ol&&li&选择相邻两个数组成一个有序序列。&/li&&li&选择相邻的两个有序序列组成一个有序序列。&/li&&li&重复第二步，直到全部组成一个有序序列。&/li&&/ol&&br&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&public static void mergeSort(int[] numbers, int left, int right) {
int t = 1;// 每组元素个数
int size = right - left + 1;
while (t & size) {
int s =// 本次循环每组元素个数
while (i + (t - 1) & size) {
merge(numbers, i, i + (s - 1), i + (t - 1));
if (i + (s - 1) & right)
merge(numbers, i, i + (s - 1), right);
private static void merge(int[] data, int p, int q, int r) {
int[] B = new int[data.length];
int t = q + 1;
while (s &= q && t &= r) {
if (data[s] &= data[t]) {
B[k] = data[s];
B[k] = data[t];
if (s == q + 1)
B[k++] = data[t++];
B[k++] = data[s++];
for (int i = i &= i++)
data[i] = B[i];
&/code&&/pre&&/div&&h1&8.基数排序&/h1&&blockquote&&p&用于大量数，很长的数进行排序时。&/p&&/blockquote&&ol&&li&将所有的数的个位数取出，按照个位数进行排序，构成一个序列。&/li&&li&将新构成的所有的数的十位数取出，按照十位数进行排序，构成一个序列。&/li&&/ol&&br&&p&代码实现如下：&/p&&div class=&highlight&&&pre&&code class=&language-text&&&span&&/span&public void sort(int[] array) {
//首先确定排序的趟数;
int max = array[0];
for (int i = 1; i & array. i++) {
if (array[i] & max) {
max = array[i];
int time = 0;
//判断位数;
while (max & 0) {
max /= 10;
//建立10个队列;
List&ArrayList& queue = new ArrayList&ArrayList&();
for (int i = 0; i & 10; i++) {
ArrayList&Integer& queue1 = new ArrayList&Integer&();
queue.add(queue1);
//进行time次分配和收集;
for (int i = 0; i & i++) {
//分配数组元素;
for (int j = 0; j & array. j++) {
//得到数字的第time+1位数;
int x = array[j] % (int) Math.pow(10, i + 1) / (int) Math.pow(10, i);
ArrayList&Integer& queue2 = queue.get(x);
queue2.add(array[j]);
queue.set(x, queue2);
int count = 0;//元素计数器;
//收集队列元素;
for (int k = 0; k & 10; k++) {
while (queue.get(k).size() & 0) {
ArrayList&Integer& queue3 = queue.get(k);
array[count] = queue3.get(0);
queue3.remove(0);
