. It took him two days to submit the code after he finished the development and passed the test. Who knows their project manager, after reading the code, ran to his desk and patted him and said, "How did you learn the data structure? What database does this real-time queuing module use? Isn't it enough to complete it in the memory. Change it now. It must be completed today and handed over to me early tomorr

One day two years ago, when I was still in college, I strolled around in a small bookstore in the school and found the big talk design model. I was immediately attracted to the design. Program The Design book can also be so interesting, so I remember the name of the interesting and easy-to-understand author, Cheng Jie.Later, on the blog of Wu fan's eldest brother, he finally asked for a ne

1. Linear table chain storage structure: Refers to the use of a set of arbitrary storage units to store the linear table data elements, this group of storage units can be continuous, or discontinuous, which means that these data elements can exist in the memory is not occupied anywhere.
2. Node: Nodes consist of data

its bottom-level implementation, in the most efficient way to complete the program, embarked on their own "into Gold Road", and reproduced please indicate the source (Baidu search "into Gold Road Blog Park").please do not hesitate to "recommend"。 3.

the calculation of the algorithm at all inputs as the computational amount of the algorithmMean time complexity: the weighted average of the calculated amount of the algorithm at all inputs as the computational amount of the algorithm(2) Spatial complexity: refers to the size of an algorithm in addition to the amount of storage space required by the input data(3) Stability: In the process of sorting the same data

After learning the bubble sort, you will find that this algorithm is constantly comparing exchange. Simple and direct, obviously gives a kind of tedious feeling. Is there any better algorithm? Of course it is, no, it sucks.:-PThis article describes a better-bubbling sorting algorithm: simple selection sortingSee " Choice " The two words estimate also guessed twos. Yes, the idea of this algorithm is that I choose to swap it for the position of the most suitable digit .In doing so, we have greatly

) . The advantages and disadvantages of static linked lists:In general, static linked lists are designed to provide a way to implement single-list capabilities for high-level languages that do not have pointers.3.13 Circular Link ListThe circular list solves a troublesome problem: How to access all the nodes of a linked list from one of the nodes. by changing the pointer of the terminal node in the single-linked list to point to the head node, the whole single-linked list is formed into a ring,

children Brother representation (binary tree) Any tree, the first child of its node if existence is the only one, its right brother if existence is also unique. Therefore, we set two pointers to the first child of the node and the right sibling of the node, respectively.
Data

Where data is the domain, FirstChild is the pointer field, storing the node

I've been thinking about two things lately. 1. Big story data structure and big talk design patternThese two books are very interesting, C language has pointers, so it is easy to understand, so suddenly think of PHP to write a familiar with the data

I. Definition of data structures: figures and structuresA class of data consists of multiple data objects, the smallest unit of which is the data element, but the data object is the unit of concern for this book of data structures

According to the book of "Big Talk data Structure", this paper realizes the Java version of the stack of the sequential storage structure, two stacks of shared space, the stack of chain storage institutions .Stack : a linear table that restricts insert and delete operations only at the end of the table.Insert (stack) a
