Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue.
Here, we will use the integers 0, 1, and 2 to represent the color red, white, and...

                                这两天要为公司一个项目的服务端写性能测试脚本,其中有一个请求订单号的接口,需要客户端用post请求向服务端发送加密过的token 和订单数据。代码如下:
payload = {'token':token,'order_data':order_data}
r = requests.post(url, data=payload}
但是,服务端返回错误,花了很长时间检查了token和order_d...

$this->load->library('session');
的同时,还需要修改配置文件:config.php 找到 $config['encryption_key'] = ‘’
将$config['encryption_key'] 的内容随便设置,就可以用了。

Given a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x.
You should preserve the original relative order of the nodes in each of the two partitions.
For example,
Given 1->4->3-...
