The title describes a domino with up to 2 blocks, each with a 1~6 point. The existing rows of n dominoes are shown.The sum of the points in the upper block is recorded as Σ1, and the sum of the points in the lower block is recorded as Σ2, and their difference is |σ1-σ2|.
Application of DancingLinks
When dancingLink is applied to actual problems, there is only one difficulty, that is, how to convert a specific problem to a 01 matrix model that can be accurately covered. Once this step is completed, directly apply the template to solve the problem.
One application: 12 computers
12 things are typical for precise coverage of dancing links, which is the easiest to understand.

Given N, it indicates that N dominoes are to be put. Each time you put down the dominoes, the probability of descending to the left is PL, and the probability of descending to the right is PR. If you fall down, all the dominoes on that side will be pushed down. You can choose to place the

Because my blog name is great_domino, many friends thought that I knew Domino technology very well and added me MSN, QQ, huh, huh! You misunderstood me. In fact, I haven't even touched Domino, let alone I don't understand it. Why should I call this name? Let me talk about it.
Domino is a western game called dominoes. All the friends who have played domino may know that i
I used a simplified method here, but it was code simplification or the sub-governance recursion idea. One is divided into 4, until 2*2 can be solved directly.
The placement of the four dominoes exactly corresponds to: dir [4] [2] = {0, 0}, {0, 1}, {1, 1}, {1, 0 }}; these four directions.
The four directions can be used to determine the four directions of the incomplete position (top left, top right, bottom right, and bottom left ).
Therefore, we can u

Problem Description
In a rectangular square box of 2xn, a 1x2 domino is filled with squares, input n, and the total number of output placement schemes. For example, when the n=3, for the 2x3 Square, Domino's placement scheme has three kinds, the following figure:

The input data consists of multiple lines, each containing an integer n, which indi
in a chessboard of 2kx2k squares, a square is different from other squares, calling it a special square and calling it a special chessboard. problem: Use 4 different forms of L-shaped dominoes to cover all squares except special squares on a given special chessboard, and any 2 must not overlap. There are 4k cases where special squares appear on the board. Thus, for any k>=0, there are 4k different special chessboard. It is easy to know that in any 2k

In a chessboard of 2^k * 2^k squares, if a square is different from other squares, it is called a special square, which is called a special chessboard. It is obvious that special squares appear on the board in the 4^k case. Thus for any k>=0, there are 4^k different special chessboard.
