fame. In contrast to working hours, writing a book is basically a loss of money to buy and sell. Needless to say, I wrote the six books Open source ebook, which is more money-losing business. Therefore, many technical Daniel are reluctant to write books . They are Daniel, not bad fame, not bad money.So if we need a technical book in one area.

ZJFC 2009-3 Programming Contest. From (0, 0) to (n-1, n-1) (left-to-right or top-to-bottom only) and then back to (0, 0) (right-to-left or bottom-up only) what is the maximum sum of vertices? Each vertex can only go once. Solution: Find the two greatest paths from (0, 0) to (n-1, n-1. Each edge capacity is 1, cost: For the vertex itself, the edge weight is the vertex weight, and the edge weight of non-vertex is 0. # Include # Include # Include Using namespace std; const int

Title Description:Given strings s and t, determine if they are isomorphic.The strings is isomorphic if the characters in s can is replaced to get t.All occurrences of a character must is replaced with another character while preserving the order of characters. No, characters may map to the same character and a character may map to itself.For example,Given "egg" , "add" return True.Given "foo" , "bar" return FALSE.Given "paper" , "title" return True.Problem Solving Ideas:Mapping with arrays.

the + number splicing string, the compiler will replace the + number new StringBuilder().append() , improve the stitching efficiency, but in a large number of loops splicing, the compiler is not smart enough, each time the generation of new StringBuilder, generating a large number of GC, so performance is not high, It is best to use conact in loops or build your own StringBuffer or StringBuilder. List interface: because the space is too long, so split, please refer to "Java Performance Opt

effective method of ensemble learning an D is one of the simplest methods of arching [1]. The Meta-algorithm, which is a special case of the model averaging, were originally designed for classification and is Usua Lly applied to decision tree models, but it can is used with any type of the model for classification or regression. The method uses multiple versions of a training set by using the bootstrap, i.e. sampling with replacement. Each of the these data sets is used to train a different mod

Well, now we are talking about big data. How can we use big data for recommendation? First of all, I think that
