PHP Print output Checkerboard implementation method, PHP print output board In this paper, we describe two implementations of the PHP print and output checkerboard. Share to everyone for your reference. The implementation method is as follows: Example 1, the code is as follows:Copy the Code code as follows: /*** Alternating color of interlaced columns* String fun_table (int $rows =9,int $cols =9)* $rows in

this case, let me introduce a method, as the title shows, a one-dimensional array to represent the checkerboard state, so how can a one-dimensional array represent a two-dimensional array?We use Tic-tac-Chess as an example:First, take a look at the two-dimensional array to represent the Tic-Tac-chess board:0 1 20 x x x1 x x x2 x x xwhere x is the representation of each position of the chessboard, 0, 1, 2 is the coordinates of each position, such as t

In the field of machine vision, camera calibration is a very basic task. At present, our frequently used calibration tools are OPENCV and MATLAB. OpenCV's Checkerboard Corner extraction API requires us to specify the horizontal points of the checkerboard in order to extract the corner points. Its main process is to take the picture two value, morphological processing, to find a number of four-sided, to eac

In a checkerboard consisting of a 2^k * 2^k, there is a square that is different from the other, and how to cover the other squares of this particular square, using the following four kinds of L-shaped dominoes.Four L-type dominoes such as 1Figure 1Special squares in the chessboard 2Figure 2The basic principle of the implementation is to divide the chessboard of the 2^k * 2^k into four 2^ (k-1) * 2^ (K-1), the special squares must be in one of the sub

As a top-notch player, he was not content with the usual chessboard and rules, so he and his good friend, Little W, decided to expand the chessboard to fit their new rules. Little Q found a rectangular piece of paper made up of squares of n*m, each of which was painted with one of the two colors of black and white. Little Q wanted to c
