Q&A

Q:如何刷本题单?

本题单分为语法入门和算法入门两部分。

1、刚学完语法,完全没有接触过算法的同学,建议先从语法入门开始练。

2、已经有过100-200道刷题量的同学,可以直接尝试直接从算法入门开始刷。

3、算法入门部分知识点全部掌握的同学,可以转算法进阶题单进行练习https://ac.nowcoder.com/discuss/828697

Q:刷题需有什么顺序吗?

题单本身就是按难度和知识点排序的,可以按顺序进行。

Q:所有的题目都要刷吗?

不一定,如果你觉得某个专题已经掌握了,可以直接进行下一个专题。

Q:刷题的时候遇到困难怎么办?

题目想了20分钟以上还是没有思路,可以尝试去找一下题解,或者看一下他人提交的代码。学会了思路以后按照自己的理解来写代码解决题目(不要对着其他人的代码来写)。题单中的题目如果在网络上找不到题解,请把题目链接回复在本贴下,我们会对题解进行补充。

Q:刷题之前需要具备什么知识吗?

语法入门部分具备学校学习的语言课程内容就可以了。在刷题的过程中逐渐熟练掌握。算法入门部分需要学会每个专题对应的算法,你可以从网络查找资料,或者跟牛客竞赛的课程进行学习 https://ac.nowcoder.com/acm/course
