The http://blog.3snews.net/space.php?uid=16796do=blogid=22870 of Jiang waves1984 Turing Award winner, the inventor of the Pascal language, Professor Niklaus Wirth, has given the program a classic definition of "program = algorithm + data structure", sharply. In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a

You must be able to read it. Algorithm base Book code example based on Python more than 400 diagrams, a vivid introduction to the implementation of the algorithm to show the advantages and disadvantages of the performance of different algorithms teach you to use common algorithms to solve daily problems faced by the actual programming

I. Problems
There are a total of five flags in the "Harry Potter" series. Assume that each volume is sold separately for 8 euros. If you purchase two different volumes at a time, you can deduct 5% of the fee, and the three volumes are more. Assume that the discount is as follows:
2 discount 5%
3 discounts: 10%
4 discounts: 20%
5 discounts: 25%
Problem: An algorithm is designed to calculate the lowest price for a batch of books purchased by the reader.

As a senior Taobao seller, do you have the following three kinds of puzzles:
1, pay close attention to Taobao search rankings, but after many years still on the ranking factor understanding fuzzy?
2, no matter how hard, sales are not low, but in the home page is still someone else's baby?
3, helpless under, in order to survive, can only rely on the through train to bring traffic, the result of the larger flow, ranking more lean on the back?
Why Taobao opened a shop for many years, still know

Said is read, but really read it, actually not, but today really do not want to write code, want to summarize.After reading the book, the book does give a lot of code, but also give a lot of examples, but really have actually to operate it, maybe when asked this question I was blindfolded.Really, in practice, no use, you learn a lot of no use, as you learn DFS and BFS, but this

main purpose is to separate the specific implementations of the abstract data types from their functions. The program must know what the operation is doing, but it's better if you don't know how to do it.tables, stacks, and queues may be three basic data structures in all computer science, and a large number of examples attest to their wide range of uses. In particular. We see how the stack is used to record procedures and function calls, and how recursion is actually implemented. It is importa

Linear can be divided intoFor a data set:If there is a hyper-planar x that can precisely divide the positive and negative samples in D into the sides of S, the hyper-plane is as follows:Then the data set D is linearly divided, otherwise, it is not possible to be divided.W is called the normal vector, which determines the direction of the super plane, and B is the displacement amount, which determines the distance between the super plane and the origin point.The distance from any point in the
