题目描述:
Given a string that contains only digits 0-9 and a target value, return all possibilities to add operators +, -, or * between the digits so they evaluate to the target value.
Examples:
"123", 6 -> ["1+2+3", "1*2 ...

Given an unsorted integer array, find the first missing positive integer.
For example,
Given [1,2,0] return 3,
and [3,4,-1,1] return 2.
Your algorithm should run in O(n) time and uses constant space.
SAE近期的优化,目前已经支持Git,本文将介绍如何使用Git在SAE上部署代码。
使用Git进行代码管理,首先要在本地安装Git客户端,下载链接:http://www.git-scm.com/download/
Git客户端的安装与配置过程在此略去不讲,谷歌一下可以找到许多相关的内容,文章重点介绍如何使用Git在SAE上部署代码。
本文例子中使用的操作系统为Windows 8.1,应用语言为Python,应用名称为gitsrc。
在首次对应用进行代码管理时,有且仅有一次选择代码库管理方式的机会,这里我们选择Git。
此后应用的代码管理方式将不可变更
创建完成后,可以在页面上看到应用的Git仓库地址:https://git.sinaapp.com/gitsrc/

Given a positive integer n, find the least number of perfect square numbers (for example, 1, 4, 9, 16, ...
) which sum to n.
For example, given n = 12
, return 3
because 12 = 4 + 4 + 4
; given n = 13
, return ...
