Print two-dimensional array in spiral order - Stack Overflow
2011年2月16日 · The idea is to treat the matrix as a series of layers, top-right layers and bottom-left layers. To print the matrix spirally we can peel layers from these matrix, print the peeled part and recursively call the print on the left over part.
algorithm - creating a spiral array in python? - Stack Overflow
2016年4月25日 · The other reason is that most of examples of producing a spiral matrix I found (including the code in the question and in the other answers) deal only with square matrices of size n x n for odd n. Finding the start (or end) point in matrices of other sizes may be tricky. For example, for a 3x5 matrix it can't be the middle cell.
algorithm - Looping in a spiral - Stack Overflow
2008年12月30日 · When you fill a matrix with the positions generated, it will generate a matrix where the center is never filled: [x][x][x] [x][0][x] [x][x][x] Technically, the spiral should start at a point and then turn edge at each possible empty spot, thus, at the end there shouldn't be any [0] If drawing Ulam spirals with this formula, that is important.
loops - Spiral matrix pattern in c? - Stack Overflow
2024年1月1日 · The matrix should be filled with the numbers X and Y as follows: in the middle of the matrix, ie at the coordinates [S/2,V/2], there is the number X (the solution will be recognized if the coordinates of the center deviate by 1 from the expected ones).
Spiral traversal of a matrix - recursive solution in JavaScript
This solution is for any kind of matrix (m * n), not just square(m * m). Below example takes 5*4 matrix and prints in spiral format.
