2d torus

Original question:A grid that wraps both horizontally and vertically is called a torus. given a torus where each cell contains an integer, determine the sub-rectangle with the largest sum. the sum of a sub-rectangle is the sum of all the elements in that rectangle. the grid below shows a torus where the maximum sub-rectangle has been shaded.1-100-423-2-3241-1503-

Uva10827-maximum sum on a torus (maximum and deformation of matrices)The main idea: is uva108 deformation, the matrix can be connected, is able to connect from the back to the front. Here The matrix is copied three times, and then once again generate a large matrix, you can solve the problem of Unicom. Then enumerate the starting and ending points of the matrix, preserving the maximum value.For example: 1 2 32 3 4New matrix: 1 2 3 1 2 32 3 4 2 3 41 2

UVA10827-Maximum sum on a torus Question Link A ring matrix is given, that is, the first row is connected to the last row. The first column is connected to the last column, and the sum of the largest child matrix is obtained. Idea: as long as four matrices are copied, the sum of the maximum submatrices in a matrix can be calculated, that is, the sum of all submatrices is enumerated and the maximum value is updated. Note that in the converted large m

Original title: A grid that wraps both horizontally and vertically is called A torus. Given a torus where each cell is contains an integer and determine the Sub-rectangle with the largest sum. The sum of a sub-rectangle is the sum of the "the elements in" that rectangle. The grid below shows a torus where the maximum sub-rectangle has been shaded. Input The

2d or not 2D-creating 2D games with unity3d Part 3 posted January 20th, 2011 in tutorials, unity3d by Tim Miller My next game is going to be 2D, but the backgrounds will be forced perspective to give the scene a 3D appearance. before the artists starts artifying the final backgrounds in Photoshop, I want to make sure t

Unity 2D Termination Manual (1)-2D project + elf _unity3d Development _ Blue GullThis article series mainly introduces Unity 2D Development technology. This includes The difference between the 2d/3d project, how to set up the 2d/3d mode, the components used in

Unity 2D Game Development QuickStart 1th creating a simple 2D gameEven now, many novice game developers, when it comes to unity, still think unity can only be used to make 3D games. In fact, when Unity released its 4.3 release in 2013, it started offering support for 2D games. For example, there are some unity tools dedicated to developing

Let's talk about the 2D implementation of the water surface effect (1) and the 2d implementation of the water surface. 0. Introduction I have always wanted to write my own understanding about the 2D implementation of water surface effects. Unfortunately, I have been dragging on for various reasons. Fortunately, some things have come to an end recently, and I have

Ngui Structure UI Root (2D) for creating a UI UI object with a camera parameter of simple 2DThe camera parameter created with Ngui is a simple 2D UI that generates 1 game objects named UI Root (2D) in the game's scene, with 3 other objects under it: Camera, Anchor, and Panel,1-4. This section describes each of the 4 game objects selected from Ngui from beginner t

2D Z 2D drawing and quartz2d drawing Quartz 2D drawing can only be rewritten to drawRect in UIView: This method is used for drawing. It is invalid in other places and an error is returned. Drawing Process: 1. Obtain the context CGContextRef context = UIGraphicsGetCurrentContext (); 2. Add the graph CGContextAddRect (context, CGRectMake (50, 50,100,100 )); 3. Draw

See "2D Matrix" this tall on the noun, some students may have a fear, "matrix", looks very advanced appearance, I still see simple bar. In fact this article is very simple, you only need to have a little CSS3 transform foundation is good.No foreplay, straight to the subject.The three-dimensional matrix refers to the elements in the 2D plane, such as scaling, panning, rotation, stretching four kinds of chang

Graphic context explanation of Quartz-2D drawing, quartz-2d Context The previous article roughly described the things in Quartz, but did not talk about the specific implementation details and how to call the corresponding API. This article describes the specific operations of the graphic Context. The so-called Graphics Context represents a drawing target, that is, the place where you plan to draw. It contai

Hello everyone, the 2d engine is based on OpenGL (ES) 3d technology, because it has many advantages over the previous DDraw! 1. Coordinate with floating-point number, can be used for curve movement 2. If the image is scaled and rotated in DDraw, it is based on pixel operation, it is very cost-performance, and 3d, it is easy to do the work! 3. It is based on rendering a panel, then pasting the stickers on the panel and then rotating and zooming the pan

Given a 2D matrixMatrix, Find the sum of the elements inside the rectangle defined by its upper left corner (Row1,Col1) and lower right corner (Row2,Col2 ). The above rectangle (with the red border) is defined by (row1, col1) = (2, 1) and (row2, col2) = (4, 3 ), which Contains sum = 8. Example: Given matrix = [[3, 0, 1, 4, 2], [5, 6, 3, 2, 1], [1, 2, 0, 1, 5], [4, 1, 0, 1, 7], [1, 0, 3, 0, 5] sumregion (2, 1, 4, 3) -> 8 sumregion (1, 1, 2, 2)-> 11

HoloLens allows us to see holographic content in the real world. But it's essentially a Windows 10 device, which means that HoloLens can run most UWP apps in the Windows Store as a 2D app.Target platform set to Windows.universaltargeting Windows.universal Microsoft's platform has been changing over the past few years, so developers tend to have different starting points, so here are some guidelines to help developers of different starting points
