大二想报名参加蓝桥杯的 c++ 比赛，但自己现在只学了课内的课程，数据结构与算法课也只上了几周，想问问以这个比赛为目的学习算法有什么推荐的路径么
The data structures courses offered on campus are generally average, with almost no practical component. If you’re interested in algorithm contests, you need to learn and practice from scratch yourself. I recommend two websites:
- OI Wiki introduces most of the commonly used knowledge points for algorithm contests.
- 洛谷 is a relatively suitable OJ (Online Judge) platform for beginners learning algorithm contests, with many problems. You can start with the official 题单, which is ordered from easy to hard.
Of course, there are many resources for algorithm contests; you can also search Zhihu for introductory questions about algorithm contests, and then look for other books or courses.
