multidimensional-array

问题 I have to add the votes per state of the 2008 elections on a 2 dimensional array, but when I run the code it sums only the first row and then keeps adding itself to the previous sum 51 times to the right side like this: State Obama McCain Other Total by state Alabama 813479 1266546 19794 2099819 2426016 72985 etc... Alaska 123594 193841 8762 2099819 2426016 72985 etc... But i needed to add the total votes on each state only once per row. public static void main(String[] args) throws

问题 Might be a newbie question but I've been trying to figure this problem and it's doing my head in. I have the following array : [0] => Array ( [provisionalBookingRoomID] => 1 [totalSpecificRoomCount] => 2 ) [1] => Array ( [provisionalBookingRoomID] => 2 [totalSpecificRoomCount] => 5 ) I need a php function that searches through the array for the value of 'provisionalBookingRoomID' and returns the value of 'totalSpecificRoomCount' basically something like the following

问题 I am having a method(function) that is supposed to add a (8*6)Array to an Array list. Function is called several times. int [][] KeySelection = new int [8][7]; for(int i=0;i<KeySelection.length;i++){ for(int j=0;j<KeySelection[0].length;j++){ KeySelection[i][j] = (int) (Math.random () * 2); } } Each time this function is called a totally new KeySelection Array is done. What i need now is to declare an array list so that it could store all the KeySelection Arrays in that list. So that when i

问题 I am fairly new to php so I am not sure of the names and terms of what I would like to find out here. I did do a search on SE but although the titles of questions are similar, they ask a completely different thing which are unfortunately not partially related even. Excuse me in advance if it exists and I could not find. I have a string $str= 'somevalue'; or an $array = ['s', 'o', 'm' ..]; Now, I have an other array which is 2 dimensional, of which 1st items I want to check against this main

问题 I have a 2D array. I want each pixel to be represented by a total of four in the actual image. I've tried various piece of code but none seem to work and I don't really understand how it works either. So far I have: panel = new JPanel() { @Override public void paint(Graphics g) { Rectangle rect = g.getClipBounds(); g.setColor(Color.white); g.fillRect(rect.x, rect.y, rect.width, rect.height); for (int i = 0; i < m.width(); i++) { for (int j=0; j < m.height(); j++) { g.setColor(Color.red); g

问题 I'm trying to wade my way through working more with multidimensional arrays to decrease the number of SQL queries I'm having to make. The problem is, they are new to me. Can someone give me some direction how to accomplish this? Here's an example of the array: Array ( [0] => Array ( [0] => 2013-07-01 [1] => Andy [2] => Hopkins Module ) [1] => Array ( [0] => 2013-07-01 [1] => Frank [2] => Rotation ) [2] => Array ( [0] => 2013-07-01 [1] => James [2] => Morning Report ) [3] => Array ( [0] =>

问题 Based on this answer, I am using the changethis method import numpy as np import os def changethis(pos): appex = sfile[pos[1]-1][:pos[2]] + '*' + file[pos[1]-1][pos[2]+len(pos[0]):] file[pos[1]-1] = appex pos = ('stack', 3, 16) sfile = np.genfromtxt('in.cpp',dtype='str',delimiter=os.linesep) changethis(pos) print(file) where the in.cpp is a source file which contains the following: /* Multi-line comment */ #include <iostream> #include <fstream> using namespace std; int main (int argc, char

问题 I need to store information similar to this: tag_array['design1']['0'][0]['x'] = 100; tag_array['design1']['0'][0]['y'] = 100; tag_array['design1']['0'][0]['w'] = 710; tag_array['design1']['0'][0]['h'] = 332; This would work if it is PHP but it's not working in javascript. How do I create the same array in proper javascript syntax? 回答1: In PHP, you can do that because it will make the parent elements too (it actually throws a warning). In JavaScript, it will error out because the parent

问题 I'm building a stream of data based on users a user is following. While I have a working prototype, the code seems unnecessarily ugly with multiple loops with further queries nested in them. I was wondering if I could get any advice on simplifying this, possible handling more within the sql query itself? On with some code: (I've trimmed this down a little and removed some of the rows retrieved). $init = $conn->prepare("SELECT followerid FROM following WHERE userid=?"); $init->bind_param("s",
