Space Time The choice of data structure and algorithm can make the difference between a program running in a few seconds or many days. What is data structure Why you come here * * * 研究数据结构,重要的一点是要明确数据内部的逻辑关系和结构 Data structure and life * More example * More ...
Put a pointer in a structure, giving the next location of the next structure. Static variable vs. Dynamic variable Static variable – declared and named in program Dynamic – created during program execution. Understanding Pointers Declare a pointer int *aPtr; int *aPtr = null; Assigning a po...
Comparison to array: Similarity: linear data structure Operations: insertion, deletion, find Difference: dynamic size vs. static size in array items are linked by references (based on many isolated but related memory spaces; array: a big piece of memory space) referenced by relationship not by p...

If one data structure or algorithm is superior to another in all respects, the inferior one will usually have long been forgotten. For nearly every data structure and algorithm presented in this book, you will see examples of where it is the best choice. Some of the examples might surprise ...
