Background: Beginners of programming will have such problems. When encountering problems, they intuitively use the logic that the computer can understand to describe the problems to be solved and the specific solution process. However, such programs are only to meet the current needs and are not easy to maintain and expand. Problem solving idea ...

Merge order: 1. It is a sort algorithm based on merge operation, which is an application of divide and conquer method 2. Steps: Assume that the sequence to be sorted is R[0...n-1], and adopt two-way merge a. divide r into two subsequences R1, R2 with the same growth or the same difference of 1 b. divide the subsequences R1 and R2 recursive ...

Title Link Make complaints Let the practice card of \ (nlog \) pass.. thinking Because \ (1 \le q \le 10^5 \), you can first label the position of each standard operation. In this way, all subscripts are within \ (10 ^ 5 \). Both multiply and add operations can be written in the form of \ (kx+b \). A prefix is then maintained for these operatio ...

Binary Tree Padding - Tree In the previous articles, the linear table, stack, queue, string, and so on, which we have mainly introduced, are one-to-one linear structures. Today we are explaining "tree" is a typical non-linear structure. The feature of the non-linear structure is that the direct precursor of any node, if it exists, mu ...

Title Link   Continuation of this blog Last Blog (Maximum Stream Dinic algorithm), this time the EK algorithm is used to solve the maximum flow problem. EK algorithm idea: Search for an extension road from source to sink in the graph, you need to record this path, increase the maximum feasible flow Liu of this path to result ans, then update ...

Close to leaving, I decided to make up for the knowledge of C++11 that I had never learned before. Suddenly, I turned to exception handling. I felt it was a little fun and wrote a test program myself. Then the three views were completely subverted.The source code is as follows: #include <iostream> #include <string> #include <exc ...

subject P1108 low price purchase analysis I'm exhausted physically and mentally. I'm almost autistic. When I was sent N, I finally understood the meaning of this sentence When two schemes "look the same" (that is, they form the same price queue), the two schemes are considered the same. There are two questions about this question. T ...
