multidimensional-array

问题 I've built a 8*2bits array to represent a piece of memory in Verilog reg [1:0] m [0:7] There is a reset signal for this memory and if reset is 1, all the bits in this memory should be reset to 0. But I don't know how to set all the bits of m in a concise way, because if there are hundreds thousands of bits in the memory, the following way is obviously unfeasible. always@(posedge clk or posedge reset) begin if (reset) begin m[0]<=2'b00; m[1]<=2'b00; m[2]<=2'b00; m[3]<=2'b00; m[4]<=2'b00; m[5]<

问题 I am using Twig with PHP. I have a multidimensional array setup like this: Array ( [Special] => Array ( [277] => Array ( [name] => First Item [quantity] => 1 [price] => 0 ) [276] => Array ( [name] => Second Item [quantity] => 11 [price] => 0 ) [278] => Array ( [name] => Third Item [quantity] => 2 [price] => 0 ) ) [Technical] => Array ( [14] => Array ( [name] => First Item [quantity] => 1 [price] => 1 ) ) [Books] => Array ( [169] => Array ( [name] => First Item [quantity] => 2 [price] => 100 )

问题 I want to do 2D dynamic ArrayList example: [1][2][3] [4][5][6] [7][8][9] and i used this code: ArrayList<ArrayList<Integer>> group = new ArrayList<ArrayList<Integer>>(); group.add(new ArrayList<Integer>(1, 2, 3)); how should i initialize this arraylist? 回答1: If it is not necessary for the inner lists to be specifically ArrayList s, one way of doing such initialization in Java 7 would be as follows: ArrayList<List<Integer>> group = new ArrayList<List<Integer>>(); group.add(Arrays.asList(1, 2,

问题 In my case I have mongodb document with nested arrays and I need to update attributes array elements. My mongodb document as follows. { "_id" : ObjectId("5dca9c5ece5b91119746eece"), "updatedAt" : ISODate("2019-11-20T11:48:55.339Z"), "attributeSet" : [ { "attributeSetName" : "test-0", "type" : "Product", "id" : "1574158032603", "updatedAt" : ISODate("2019-11-19T10:10:53.783Z"), "createdAt" : ISODate("2019-11-19T10:07:20.084Z"), "attributes" : [ { "attributeName" : "test-attribute",

问题 I have a dataset which has 4 dimensions (for now...) and I need to iterate over it. To access a value in the dataset , I do this: value = dataset[i,j,k,l] Now, I can get the shape for the dataset : shape = [4,5,2,6] The values in shape represent the length of the dimension. How, given the number of dimensions, can I iterate over all the elements in my dataset? Here is an example: for i in range(shape[0]): for j in range(shape[1]): for k in range(shape[2]): for l in range(shape[3]): print(
