Question Link Give N and M, and find F (n) % m. f (x) is the Fibonacci sequence. Idea: Because N is big, it is very likely that it will use the formula to calculate it, so we can use the Matrix to quickly solve the power. | (1, 1), (1, 0) | * | f (n-1), F (n-2) | = | f (N), F (n-1) |, so f (N) equivalent to | F (1), F (0) | multiplied by N-1 | (1, 1), (1, 0) |. Code: #include Uva10299-modular Fibonacci

The meaning is to use matrix multiplication to find the last four digits of the nth of the Fibonacci series. If the last four digits are all 0, the output is 0. Otherwise Remove the leading 0 from the last four digits of the output... ... Yes... ... Output FN % 10000. The question is so clear .. I am still trying to find the last four digits of % and/and determine whether all the values are 0 and whether the output values are 0. Remove the leading 0.

In the morning to think of an algorithm problem, think of the eight queen recently saw the problem, on the Internet search information, also according to the algorithm written by the previous one side, I think the structure is very clear, recursive backtracking is very convenient to solve the problem. Now put the code and comments on your own to review and summarize.A. Description of the problem:Place the N-Queens that are not attacked by each other o

first, the purpose of the experiment: To solve the problem of eight queens with backtracking method. second, the experimental content: 1, read the C language writing backtracking method to solve the eight Queen problem code. 2, reference C language code, using MATLAB to write backtracking method to solve the eight Queen problem code. 3, require comments on the key code, annotated line requirements of 1/3.

Use STL to implement deep search and wide search -- N Queen's question exampleTwo days ago in the sharpdew blog (http://blog.csdn.net/sharpdew) saw the n queen problem article, sharpdew algorithm is very beautiful, high efficiency. I just want to try my DFS/BFS algorithm from the test point of view, so I tried to write it. But I can tell you that my program is at least several times slower than sharpdew. I think the reason is that STL containers (such
