above three are the biggest problems of LZ, or the process of LZ self-recognition. In fact, LZ's character as a leader also has many advantages. This boast will not be nonsense here, But LZ personally feels that recognizing its own advantages is equally important as recognizing its own shortcomings. Just like a sentence in LZ's previous blog post, it is natural for me to be useful, but I am afraid that you will never know what you are using. Although LZ is already trying to change, it can be ch

time is longer than 1+10e16 years. Such a long time, in the actual completion is unimaginable. Third, simulated annealing algorithm Simulated annealing algorithm is one of the effective methods to solve TSP problem, its initial thought was proposed by Metropolis in 1953, Kirkpatrick successfully applied it in the combinatorial optimization problem in 1983. The simulated annealing algorithm is derived fr

1005ac+ Problem Solving Ideas Analysis: 1, in the title (1 2, (A * f (n-1) + B * F (n-2)) MoD 7 = (a%7*f (n-1) +b%7*f (n-2))%7 3, because F (i) and F (i+1) have only 49 combinations, because (f (i), (i+1) There are only 7 options, that is, only one of the 0,1,2,3,4,5,6. Therefore, the cycle Solving: 1, the cycle is first, by the way, the first period

Problem Solving report POJ3463 ACM computer FactoryDescriptionAs you know, all the computers used for ACM contests must is identical, so the participants compete on equal terms. That's why all these computers was historically produced at the same factory.Every ACM computer consists of P parts. When all these parts was present, the computer is ready and can be shipped to one of the numerous ACM contests.Comp

Problem Solving report POJ2769 reduced ID NumbersDescriptionT. Chur teaches various groups of students at university U. Every u-student has a unique student identification number (SIN). A SIN S is an integer in the range 0≤s≤maxsin with Maxsin = 10 6-1. T. Chur finds this range of SINs too large for identification within her groups. For each group, she wants to find the smallest positive integer m, such thi

The object-oriented thinking method is actually the way of thinking we get used to in real life, starting from the perspective of human consideration, the process of translating human thinking for solving problems into a way of thinking that can be understood by the program. In this process, the software is gradually designed. In the process of using object-oriented thinking methods for software design, the most common mistake is to start the analysi

Select several plus tags from these points. Requirements: For each point, there must be a marked point (including itself) within the range of R. At least how many points must be marked to satisfy the requirement. Input: N, R, and the distance from the origin of N points (① does not necessarily

[Problem Discovery]The project requires several custom controls. Cainiao D defines an interface and intends to use polymorphism for unified calling. After two custom controls are completed, the project can run normally. However, when using the third Control, a problem occurs: After dragging the control to the interface, you cannot drag it to change the width of the control, A prompt "cannot create a ne

executed, rows are retrieved from other tables. Find Max () or min () values for a specific index columnSort or Group A table if sorting or grouping is done on the leftmost prefix of an available key (for example, order by key_part_1,key_part_2). If all key values are partially followed by DESC, the key is read in reverse order. In some cases, a query can be optimized to retrieve values without consulting the data file. If all columns used for some tables are numeric and form the leftmost prefi
