题目描述:
Given an unsorted array of integers, find the length of longest increasing subsequence.
For example,
Given [10, 9, 2, 5, 3, 7, 101, 18]
,
The longest increasing subsequence is [2, 3, 7, 101]
, therefore the length is 4
. Note ...

通过SAE的海外代理绑定独立域名,有时会遇到服务不稳定的情况,导致应用无法访问。
此时,如果手边恰好有一台可用的位于海外的Linux服务器,可以通过Nginx服务器为SAE应用搭建一个临时的反向代理,以解燃眉之急。
以CentOS系统为例,首先使用yum安装nginx服务器:
[root@localhost ~]# yum install nginx
然后更改nginx配置文件:
vi /etc/nginx/conf.d/default.conf
将location / {...}代码段替换为如下内容(<<APP_NAME>>替换为应用名):
location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Forwarded-Host $remote_addr; proxy_pass http://<<APP_NAME>>.sinaapp ...
You are playing the following Bulls and Cows game with your friend: You write a 4-digit secret number and ask your friend to guess it, each time your friend guesses a number, you give a hint, the hint tells ...
托管在SAE上的Django应用,如果使用共享型MySQL数据库服务,可以通过配置数据库路由,实现读写分离。利用SAE从库的价格优势,减少云豆开销。
新浪云SAE共享型数据库支持读写分离(Read/Write Splitting),即主数据库(Master)处理事务性增、改、删操作(INSERT、UPDATE、DELETE),而从数据库(Slave)处理SELECT查询操作。
并且从SAE共享型MySQL的使用价格上来看:
共享型MySQL(主库) 请求次数10000次 400云豆/百万次 4元/百万次 磁盘容量20MB 5云豆/GB/天 0.05元/GB/天 共享型MySQL(从库 ...
Given a binary tree, find the maximum path sum.
For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The path does not ...
