jagged-arrays

问题 Using C#, I have a 2D Jagged array containing objects, what I want to achieve is to sort this Jagged array based on a public property within these objects I have created a sample below of my problem, I have limited experience with using LINQ, but I have attemped using it and have failed, I have also proceeded to create a swap method if needed. Any insight would be much welcomed, thank you //[][] of Objects private MyObject[][] jaggedArray = new MyObject[3][] { new MyObject[5] { new MyObject()

问题 I have 2D jagged array. And I want to sort it by any rows. I've searched and found code for sorting by columns private static void Sort<T>(T[][] data, int col) { Comparer<T> comparer = Comparer<T>.Default; Array.Sort<T[]>(data, (x,y) => comparer.Compare(x[col],y[col])); } Can I adapt it for sort by any rows ? Any help is appreciated. Sample of my jagged array (Added) using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication3 { class

问题 Essentially I'm not sure how to store a 3D data structure for the fastest access possible as I'm not sure what is going on under the hood for multi-dimensional arrays. NOTE: The arrays will be a constant and known size each and every time, and each element will be exactly 16 bits. Option one is to have a multi-dimension array data[16, 16, 16] and simply access via data[x, y, z] option two is to have a single dimension array data[16 * 16 * 16] and access via data[x + (y * 16) + (z * 16 * 16)]

问题 I have a jagged array and I need to sort it by the column "2": example: array[x][2] What I have is about 64 where the "x" is and in the second column (where the "2" is) I have 4 different options, but I need to sort by the second option. 回答1: Just use OrderBy : array = array.OrderBy(inner => inner[2]).ToArray(); If it's important to use an in place sort then you can use Array.Sort : Array.Sort(array, (first, second) => string.Compare(first[2], second[2])); 来源： https://stackoverflow.com

问题 I am finishing up a program but having a bit of trouble with one last aspect. In this part of the program, I am testing to see if the array is jagged (same number of rows and columns). I want to use a nested for loop to do this but am having trouble with the logic and structure. For example, the following array is jagged: 1, 2, 3 4, 5, 6 7, 8, 9, 10 And the following array is not: 1, 2, 3 4, 5, 6 7, 8, 9 Can anyone offer guidance on how to do this? 回答1: Start with being clear about what a

问题 I am new to Python and I am looking for the most efficient way to do operations with a jagged array. I have a jagged array like this: A = array([[array([1, 2, 3]), array([4, 5])],[array([6, 7, 8, 9]), array([10])]], dtype=object) I want to be able to do things like this: A=A[A>4] B=A+A Apparently python is very efficient for doing operations like this with numpy arrays, but unfortunetely I need to do this for jagged arrays and I havent found such an object in Python. Does it exist in Python,

问题 What is the difference between ragged and jagged arrays? As per my research both have the same definitions, i.e. two-dimensional arrays with different column lengths. 回答1: Your question already says the correct answer ^^ but for completeness. A Jagged or also called Ragged array is a n-dimensional array that need not the be reactangular means: int[][] array = {{3, 4, 5}, {77, 50}}; For more examples you could look here and here! 回答2: Jagged array is array of arrays such that member arrays can

问题 In the game I am making, I have a level that is created through an XML file. The level is drawn with a nested for loop. I am trying to make another nested for loop to take the position of each tile and assign it to a jagged array. I want to do this so I can make collision detection for each tile. Each tile in the picture of the example level below is 20x20 pixels, with 30x30 tiles, for a screen resolution of 600x600. The level was made with the free software Realm Factory, which lacks
