 Compared with CS106B/X (Data structures and algorithms using C++), 6.006 emphasizes the algorithms more. It also covers several classical data structures such as AVL trees. You may use it to learn more about algorithms after CS106B/X.
 
-相比较于斯坦福的CS106B/X（C++描述的数据结构与算法），该课程更侧重于算法方面的详细讲解。课程也覆盖了一些经典的数据结构，如AVL树等。个人感觉在讲解方面比CS106B更加详细，也弥补了CS106B在算法方面讲解的不足。适合在CS106B入门之后巩固算法知识。
