multidimensional-array

问题 Hi and thank you very much for your help. I'm new to swift and have thoroughly researched the other answers but they all are not working for me. I have sample data in the format: ["10-24-2015", "124", "Yes", "No", "No", "Yes", "Yes", "NA", "NA"] There are only 3 entries with varying dates and values and they're all in a master array. It's been written to a file already and so I start my code below from a loaded file. All I would like to do is to sort the arrays by date which is the first

问题 I have a piece of multidimensional array output like this: Array ( [0] => Array ( [item] => null [count] => 0 [child] => Array ( [Dagadu Bocah] => Array ( [item] => Dagadu Bocah [count] => 47 [child] => Array ( [HirukPikuk] => Array ( [item] => HirukPikuk [count] => 5 [child] => Array ( [DGD] => Array ( [item] => DGD [count] => 1 [child] => ) ) ) In my expectations, I can use the unset function in the foreach loop to delete each array that has 3 keys, namely 'item', 'count' and 'child' so

问题 I want to pass this two dimensional array of pointers to a function: array: *cmd[maxCmdSize][maxArgSize] function: void performCmd(char *cmd[maxCmdSize][maxArgSize]) How to achieve this without declaring the size of the dimensions in the function? 回答1: With VLA parameters (VLAs, i.e., variadic-length arrays, are an optional standard extension of C11), you can pass the size as another parameter (which needs to preceede the VLA). The innermost index, where the array decays to a pointer (an int

问题 I have the following structure in my excel sheet. E F G H --------- --------- ------ ------- 2 | blah sometext atext smth 3 | textval accc 4 | test avfr 5 | check 6 | ertyui 7 | Can you suggest a way using EXCEL functions ( not VBA ) of getting back the row of a matching string? For example: given test I need to get back 4 , given ertyui 6 I need: the lookup to be done in all the columns of this two-dimensional array and have the function in one cell only 回答1: With your search string in A1:

问题 I have a string with a variable number of key names in brackets, example: $str = '[key][subkey][otherkey]'; I need to make a multidimensional array that has the same keys represented in the string ( $value is just a string value of no importance here): $arr = [ 'key' => [ 'subkey' => [ 'otherkey' => $value ] ] ]; Or if you prefer this other notation: $arr['key']['subkey']['otherkey'] = $value; So ideally I would like to append array keys as I would do with strings, but that is not possible as

问题 Similar to this answer, I have a pair of 3D numpy arrays, a and b , and I want to sort the entries of b by the values of a . Unlike this answer, I want to sort only along one axis of the arrays. My naive reading of the numpy.argsort() documentation: Returns ------- index_array : ndarray, int Array of indices that sort `a` along the specified axis. In other words, ``a[index_array]`` yields a sorted `a`. led me to believe that I could do my sort with the following code: import numpy a = numpy

问题 This very basic code prints my 2D array row by row. public class scratchwork { public static void main(String[] args) throws InterruptedException { int[][] test = new int[3][4]; for (int row = 0; row < 3; row++) { for (int col = 0; col < 4; col++) { System.out.print(test[row][col] = col); } Thread.sleep(500); System.out.println(); } } } How can I edit the loops to print the array column by column? Edit: just want to clarify that the output is 0123 .... 0123 .... 0123 with the dots

问题 I a having a little trouble with vector or array operations. I have three 3D arrays and i wanna find the average of them. How can i do that? we can't use mean() as it only returns a single value. The more important is some of the cells in the arrays are NA whic mean if i just add them like A = (B + C + D)/3 The results of will show NA as well. How can i let it recognise if the cell is NA then just skip it. Like A = c(NA, 10, 15, 15, NA) B = c(10, 15, NA, 22, NA) C = c(NA, NA, 20, 26, NA) I

问题 My array looks like this: Array ( [1] => stdClass Object ( [id] => 225 [user_id] => 1 [name] => Blue Quilted Leather Jacket by Minusey - $499 ) [2] => stdClass Object ( [id] => 222 [user_id] => 1 [name] => Darling New Bathtub by Duravit - $6300 ) [3] => stdClass Object ( [id] => 222 [user_id] => 1 [name] => Darling New Bathtub by Duravit - $6300 ) ) I have an array of products that I need to make sure are unique. Need to make this array unique by id. These array are generated by pushing value
