multidimensional-array

问题 I have 3 arrays for storing posts,comments, and likes. These are the JSON strings: //comments JSON (stores user and comment points) $comments='[ { "user": "5", "points": "12" }, { "user": "2", "points": "1" }, { "user": "3", "points": "1" } ]'; //likes(stores user and likes point) $likes='[ { "user": "1", "points": 7 }, { "user": "4", "points": 4 }, { "user": "3", "points": 1 } ]'; //posts (stores user and post points) $posts='[ { "user": "1", "points": "6" }, { "user": "3", "points": "2" },

问题 I am writing a short program which will eventually play connect four. Here it is so far, pastebin There is one part which isn't working. I have a jagged array declared on line 16: char[][] board = Enumerable.Repeat(Enumerable.Repeat('-', 7).ToArray(), 7).ToArray(); Which I think looks like this: ------- ------- ------- ------- ------- ------- ------- when I do this board[5][2] = '*' I get --*---- --*---- --*---- --*---- --*---- --*---- --*---- instead of what I'd like: ------- ------- -------

问题 I have seen answers about this question but no one helped me. Some used numpy , and some people answered using other platforms that help Python to be simpler. I don't want these type of things, I want with the simple Python without importing libraries or anything more. Let's say: I would want to do a method that checks if there's at least one column in the 2D array that the column has the same values. For example: arr = [[2,0,3],[4,2,3],[1,0,3]] Sending arr to my method would return True

问题 I am preparing for OCAJP exam, I got a problem with the multi-dimensional arrays in java. After go through a video tutorial on YouTube, I think I got an idea about how it works. It says the following statement creates two double dimensional arrays and one array to hold both arrays. Hence it is a three dimensional array. int arr[][][] = new int[2][4][3]; So I want to get confirmed, that if I want a five dimensional array, this statement would do it. int arr[][][] = new int[4][4][3]; 回答1: Try

问题 is there any algorithm or method of generating the adjacency matrix for a hypercube for any dimension? say your input is 5 it would create a 5-dimensional hypercube all i can find are sources from wiki and wolfram 回答1: If you want to generate the vertices of a N-D unit hypercube, you can basically make an N-value truthtable. Here's some code I use for that: function output = ttable(values) output = feval(@(y)feval(@(x)mod(ceil(repmat((1:x(1))', 1, numel(x) - 1) ./ repmat(x(2:end), x(1), 1)) -

问题 I am new to this. I am learning ZF2 where I need to form a nested multi dimensional array from database values. My database table: +-------------+----------------+---------------------+--------+ | category_id | name | parent_category_ids | status | +-------------+----------------+---------------------+--------+ | 1 | New Category | 1 | 1 | | 3 | ddd | 1 | 1 | | 4 | test1 | 3 | 0 | | 5 | Test123 recipe | 3 | 1 | | 6 | abceg | 3 | 1 | | 7 | xyz | 6 | 1 | +-------------+----------------+--------

问题 I'm trying to match subcategories with their respective parent categories. For now I just hard-coded in the main categories on the view (Books, Clothes etc) and have a function to get all subcategories, then in the view I can make a while loop to match every subcategory with its main one. I've managed to get the data I want into an array, which now looks like this: array 1 => array 1 => string 'Medicine' 2 => string 'Fairy tales' 3 => string 'Novels' 2 => array 44 => string 'Men's Clothing'

问题 I would like to create something like a pointer to a 2 dimensional array of pointers (with the width and the height of x ). Will this code do what I expect? (Create array elements, writing out some information about them, then release all the allocated memory.) int main(int argc, char** argv) { int x = 3; Node ***array = new Node**[x]; for (int i = 0; i < 3; i++) { array[i] = new Node*[x]; for (int j = 0; j < x; j++) { array[i][j] = new Node(i, j); /* Node::Node(int row, int col) */ } } /* ..
