multidimensional-array

问题 I am trying to read in a string from a file, extract individual characters and use those characters to fill a 2D char array. So far I have been able to do everything except fill the array. I keep getting an Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: error message. Any help would be appreciated. This is my first time working with 2D arrays. Thanks. Here are the contents of the test.txt. Each word on a new line. The first 2 integers are the dimensions of the array 4 4

I have multi-dimension array like: Array ( [name] => Array ( [0] => South Africa [1] => Australia [2] => Egypt ) [img] => Array ( [0] => sa-flag.jpg [2]

问题 I have a array like the bellow. Array ( [1] => Array ( [TotalPosts] => 46 [AgentSchemeNumber] => 11 [AgentName] => Vaiji ) [2] => Array ( [TotalPosts] => 3 [AgentSchemeNumber] => 22 [AgentName] => Vaiji ) [3] => Array ( [TotalPosts] => 0 [AgentSchemeNumber] => 33 [AgentName] => Vicky ) [4] => Array ( [TotalPosts] => 0 [AgentSchemeNumber] => 44 [AgentName] => Raja ) [5] => Array ( [TotalPosts] => 18 [AgentSchemeNumber] => 55 [AgentName] => Rama ) [6] => Array ( [TotalPosts] => 13

问题 I've had to ask this one again, sorry, but I'm having a problem trying to process this array. I have tried several different ways but none where right, here's the array: Array ( [search] => Array ( [response] => Array ( [errors] => [number_of_hotels] => 1 of 1 ) [lr_rates] => Array ( [hotel] => Array ( [hotel_ref] => 3116 [hotel_currency] => [U] => USD [hotel_rooms] => Array ( [room] => Array ( [ref] => 6382 [type] => 1 [type_description] => Standard [sleeps] => 8 [rooms_available] => [adults

问题 Good day, I have been playing with this problem for some time now, and can't seem to analyze how to output the array probabilities, using PHP or javascript, had anyone manage to solve this problem, thanks in advance example: $arrayNms = [ ["A", "B", "C"], ["Q", "P"], ["CC", "C3"] ]; /* OUTPUT A, Q, CC A, Q, C3 A, P, CC A, P, C3 B, Q, CC B, Q, C3 B, P, CC B, P, C3 C, Q, CC C, Q, C3 C, P, CC C, P, C3 */ //this is what I got so far, but can't seem to output the desired values $arr1 = []; for ($i

问题 I'm having problems copying a multidimensional vector, I've tried many things but this is the last one: vector < vector < int > > a; vector < vector < int > > b; a.resize(10); b.resize(10); a[0][0] = 123; copy( a.begin(), a.end(), back_inserter(b) ); cout << b[0][0]; I'm trying to do a recursive loop that counts all possible routes in a grid within 10 moves. I'm trying to create a vector called current_path which would hold the current path for each recursion, when the current_path has 10

问题 Im having trouble iterating thru this array of product information with the desired result of echoing google ecommerce tracking code for each item. How do I reduce the dimension by one. In short - How do turn this: Array ( [array] => Array ( [0] => Array ( [product_id] => 7 [prod_count] => 1 [price] => 19.99 ) [1] => Array ( [product_id] => 6 [prod_count] => 3 [price] => 19.99 ) [2] => Array ( [product_id] => 5 [prod_count] => 2 [price] => 19.99 ) [3] => Array ( [product_id] => 4 [prod_count]

问题 Ok I really need help with all of this, I have a class named Board.java The board is represented as a two-dimensional array of char’s. A turtle can leave a trail by writing a character into each position on the board that it passes through. There will be two constructors for the board. The default constructor takes no arguments and will create a board with 10 rows and 25 columns. Set each element in the board to be a blank space. The second constructor will take two integers that specify the
