Algorithm(算法与数据结构之美)@Java@C++

Yitong WANG is a code farmer, he is good at debuging and English speaking. Yitong WANG decided to make efforts to improve his algorithm design ability, and this repository helps a lot.

Repository Content

There are several parts in this repo:

  • CS208OJ: The lab exercise of CS208: Algorithm Design and Analysis (ADA) by Prof.Yuhui SHI and Mrs.Yao ZHAO in 2021 Spring
  • FastIO: The fast reading and outputing template design by Yitong WANG using Java language, since Scanner and System.out is low-efficiency
  • JCoderAC: The lab exercise of CS203: Data Structure and Algorithm Analysis (DSAA) by Prof.Ran CHENG in 2021 Spring
  • PTA_Answer: The basic programming exercise in PTA, which is very simple
  • SUSTechACM: The exercise in SUSTechACM OJ, which is challenging
  • SYZOJ: The exercise in SYZOJ, which is not too difficult
  • Leetcode: The answer of Leetcode questions, and Yitong WANG mainly focuses on this part
  • Luogu: The anlgorithm questions on Luogu, which is challenging

Why does Yitong WANG want to improve his ability of algorithm design and analysis?

1. Algorithm can improve your ability about:

  1. Abstracting Problems(问题抽象能力)
  2. Solving Problems(问题解决能力)
  3. Coding(编码能力)
  4. API Understanding(API理解能力)
  5. Debugging(调试能力)
  6. Testing(测试能力)
  7. Understanding Ideas(思想理解能力)

2. Algorithm can help avoid those wrong cases in the future:

  1. Memory Leak(内存泄漏)
  2. Stack Overflow(栈溢出)
  3. Infinity Loop(死循环)
  4. Array Index out of Bounds(数组越界)
  5. Integer Overflow and Floating Point Error(整形溢出和浮点误差)
  6. Uninitialized Variables(未初始化变量)
  7. Incorrect Boundary Handling(非法边界处理)
  8. Infinity Recursion(无限递归)
  9. Ambiguous Variables(二义变量)
  10. Priority of Operators(运算符优先级)
  11. Cache Hitting and Missing(缓存命中与丢失)
