About the 编程与数据结构助理 certification
本助理级认证将编程直觉转化为严谨的算法判断力。你将学会用大 O 表示法（包括均摊分析）分析时间复杂度和空间复杂度；选择并理解核心数据结构——动态数组、单链表与双链表、栈、队列与双端队列、哈希表、二叉搜索树及平衡变体（AVL 树、红黑树）、堆、字典树和图；实现并比较经典排序算法（冒泡排序、插入排序、选择排序、归并排序、快速排序、堆排序）的复杂度与稳定性；正确应用线性查找与二分查找；以及运用随处可见的解题模式——递归与回溯、分治法、动态规划（记忆化与制表法）、贪心算法、双指针、滑动窗口、位运算和字符串算法。考试侧重代码阅读与复杂度分析：你需要追踪伪代码、Python 和 JavaScript 代码片段，并在约束条件下选择合适的数据结构。这些是每位优秀工程师在面试和生产系统中都必备的核心基础能力。
What you will learn
The official 编程与数据结构助理 study course covers:
- Thinking in Big-O — Measure algorithms by how they scale: complexity classes, how to analyse code, and amortised cost.
- Linear Structures — Arrays and dynamic arrays, singly and doubly linked lists, and the stack/queue/deque family.
- Hash Tables, Trees, and Heaps — Hashing and collisions, binary search trees and balancing, heaps and tries.
- Graphs and Traversal — Representing graphs, BFS vs DFS, and ordering/shortest-path algorithms.
- Sorting and Searching — The simple and efficient sorts compared by complexity and stability; linear and binary search.
- Problem-Solving Patterns — Recursion and divide-and-conquer, dynamic programming, greedy, two pointers, sliding window, bit tricks, strings, and choosing the right structure.
- 动手实验——结构、大 O 与遍历 — 在 Google Colab 中完成的数据结构顶点项目：实证测量算法复杂度，实现栈/队列/链表，使用哈希表/树/堆，并使用 BFS/DFS 遍历图以解决实际问题。纯 Python，免费运行。
