### 清华大学:陈文光 ###

**CSP考什么**  
基本的编程  
数据结构  
算法  
调试能力（实践）

**CCSP**  
内存空间  
读写数据  
网络通信  
性能优化

**工程能力**  
参与现有软件的编写  
测试  
与客户沟通  
设计审查  
团队合作等

--------------------

**题目难度描述**

第一题:单循环+分支语句即可完成，例如给出输入数据中偶数的个数.  
第二题:可能需要多重循环/或对数据进行排序等常见操作，例如点击窗口问题  
第三题:不具备算法难度，但具有一定工作量，例如命令行选项分析  
第四题:具备一定算法难度，例如广度优先图遍历算反、最短路径算法，但从题目到算法的映射不难  
第五题:不仅具备算法难度，如动态规划算法，将题目抽象到算法模型也有难度

前两题是送分题  
如果不能得分  
说明缺乏基本编程技能，或对0J方式不熟悉  
如果不能得满分  
说明编程对边界条件的考虑不完整
