I'm looking for some tool to give me a recursive diff of two arrays. What I envision is a web page with two color-coded tree-structures. On each tree, green are parts of the array which match in both arrays, and red is for parts of each that don't match the other. Something like the output of dBug I have some code that gives me a nested...
I have custom object MyClass and I need to create 3 instances of it. Instead of doing something dumb like: MyClass instance1 = new MyClass(); MyClass instance2 = new MyClass(); MyClass instance3 = new MyClass(); Shouldnt I be able to do something like this: MyClass[] instances = new MyClass(); instances[0].somemethod; ? ...
The array has to be on the stack, and I need to modify the elements. Here is what I have: Class Me { private: int *_array; void run(){ for (int i = 0 ; i < 10; ++i) { _array[i] += 100; } } public: Me(int array[]) { _array = array; } }; This is main: int array[10] = {0, 1...
I have an array that might look like this: ANOVAInputMatrixValuesArray = [[ 0.96488889, 0.73641667, 0.67521429, 0.592875, 0.53172222], [ 0.78008333, 0.5938125, 0.481, 0.39883333, 0.]] Notice that one of the rows has a zero value at the end. I want to delete any row that contains a zero, while keeping any row that contains non-zero v...
How do I properly bubble sort through a text file by assigning the values to an array. In the code below I tried to assign the values from the text file to a string while there is still something to fetch. Then I used a for loop to assign the one that I have fetch to the array. Then tried to use the bubble sort to hopefully sort the numb...
I've got an array A of D unique (int, int) tuples. I need to know if the array contains (X, Y) value. Am I to implement a search algorithm myself or there is a standard function for this in Scala 2.8? I've looked at documentation but couldn't find anything of such there. ...
Given this array int [] myArray = {5,-11,2,3,14,5,-14,2}; I must be able to return 3 because the longest down sequence is 14,5,-14. What's the fastest way to do this? PS: Down sequence is a series of non-increasing numbers. ...
I was wondering if it is possible to grab a String[] of an unknown size from a class using the java reflection API and store it elsewhere? Thanks. ...
I define a 2D array in my header file char map[3][3]; How can I initialize the values in the class constructor like this map = {{'x', 'x', 'o'}, {'o', 'o', 'x'}, {'x', 'o', 'x'}}; ...
How do you use a string array as a parameter in C? If I were to write a function with signature: Guess i didnt explain myself very well... I'll post the code that i'm trying to get to work. int format_parameters(char* str) { char local_str[201] = ""; int i = 0; int j = 0; int flip = 0; while(str[i]) { if(...
I want to ask a Java String[] question. In the java, if a variable convents to another, it can add the (String), (int), (double),... before the variable in the left hand side. However, is there something like (String[]) in Java as I want to convent the variable into (String[]). ...
Hello, I'm trying to represent an array of evenly spaced floats, an arithmetic progression, starting at a0 and with elements a0, a0 + a1, a0 + 2a1, a0 + 3a1, ... This is what numpy's arange() method does, but it seems to allocate memory for the whole array object and I'd like to do it using an iterator class which just stores a0, a1 and ...
Hi, How does one add rows to a numpy array? I have an array A: A = array([[0, 1, 2], [0, 2, 0]]) I wish to add rows to this array from another array X if the first element of each row in X meets a specific condition. Numpy arrays do not have a method 'append' like that of lists, or so it seems. If A and X were lists I would merely...
I recently started to think of this problem and I can't find the answer. The following code compiles and executes as expected object[] test = new string[12]; However, I don't know why. I mean, should we consider string[] as the derived class of object[]? I think in C#, every array is an instance of Array class. If Array is generic, i...
Hi I need to create 2D jagged array. Think of a matrix. The number of rows is known, the number of columns is not known. For example I need to create array of 10 elements, where type of each element string[]. Why do I need that? The number of columns is not known - this function must simply do the allocation and pass array to some other...

Hello, Is there a way I can initialize the following runtime array to all trues without looping over it using a foreach? Here is the declaration: bool[] foo = new bool[someVariable.Count]; Thanks! ...
To find the three greatest elements in an array(length 100), is a combination of a for loop and an if statement(s) the most effective way, or is there a more efficient method? ...
Hi everyone I'm doing a javascript assignment and have just learned that I can do it in jQuery if I wish, rather than vanilla javascript. I thought I'd give it a go to see what it's like. This is the contents of my javascript function: rowsArray = $("#Table1 tr"); for (i=0;i<rowsArray.length;i++){ numSeatsInRow = rowsArray[i]...
