Description gives the N rectangle (1≤n≤100) and its length and width (not more than 1000), write a program to find the largest k, so that there is a K rectangle satisfies the layer contains the relationship, that is, the inner rectangle is
In the previous article I talked about how to draw rectangles and circles, and they all have native canvas drawing functions to complete. In this paper, the rounded rectangle is only simulated by other methods.A normal rounded rectangle, let's first assume that the fillet of his Four corners is the same--because it's a good picture. By using the ability to split the face into lines, it is easy to see that t
Poj address: http://poj.org/problem? Id = 3494 Summary
The description of the question is very simple. In an M * n matrix, all elements are only 0 and 1, and the largest rectangle containing only 1 is found.
For example, a 4x6 rectangle is shown in the figure, and the red area is the area we want to find.
I first saw this topic in reading the surface Sutra written by a person. At that time, I had
Rectangle function: Creates a two-dimensional rectangular object.Rectangle (' Position ', [x,y,w,h])Draws a rectangle of width W high h from the point (x, y) and assigns a value to the Axis data unit.Notice that the rectangle is displayed at a specified scale, and you need to set the axis data aspect ratio so that the x and Y axes have equal units of length. You
You can use the rectangle drawing function of the drawing environment to draw a rectangle fillRect to draw a solid rectangle, strokeRect to draw a hollow rectangle, and clearRect to clear the specified rectangular area to make it completely transparent, the sample code is as follows:

Squares and rectangles fascinated the famous Dutch painter Piet Mondriaan. one night, after producing the drawings in his 'toilet series' (where he had to use his toilet paper to draw on, for all of his paper was filled with squares and rectangles ), he dreamt of filling a large rect
first represent the direction of vector A, and then the fingers swing in the direction of the palm
Vector a × vector B = | I j k || X1 Y1 Z1 || X2 Y2 Z2 |= (Y1z2-y2z1, x2z1-x1z2, x1y2-x2y1)
(I, j, and K are the unit vectors of the three vertical coordinate axes in the space)
The outer product of a vector does not conform to the multiplication exchange rate.

Determines whether a vertex is in a rectangle
Title DescriptionDefines a rectangular class that includes the lower-left and upper-right coordinates, defines the member functions that include the necessary constructors, the functions that enter the coordinates, and the functions that calculate and output the rectangular area. Requires that the test function given in the hint be used and must not be altered.InputFour numbers, representing the coordinates of the lower-left and upper-right vertices of the r
largest Rectangle in a histogramA histogram is a polygon composed of a sequence of rectangles aligned at a common base line. The rectangles has equal widths but could have different heights. For example, the figure on the left shows the histogram that consists of rectangles with the Heights 2, 1, 4, 5, 1, 3, 3, Measured in units where 1 is the width of the rectangles:
Usually, histograms is used to represent discrete distributions, e.g., the fre
Determine whether a rectangle and a circle are intersecting
Ideas:
Method 1: first determine whether the rectangle is in the circle (whether the four vertices of the rectangle are in the circle). If so, otherwise, judge whether the shortest distance from the center of the circle to the four sides of the rectangle (th
[IOS development-57] case improvement: block animation, removeFromSuperview of controls, use layer to set rounded rectangle and apply proxy mode,
Based on the above case, the case is improved: [iOS development-50] uses the creation of new classes to implement code encapsulation, so that a simple MVC experiment can be practiced without knowing it, with an animation attached
In the above case, we finally implemented an animation. clicking the "Download
Convex Polygon minimum perimeter external rectangle
This problem is similar to the smallest area external rectangle. Our goal is to find an external polygon in the smallest box (for perimeter ).P.
What is interesting is that the minimum area and the external rectangle of the minimum perimeter usually overlap. Some may wonder if this is always true. The followi

201312-3The problem description places n adjacent rectangles on the horizontal axis, each rectangle having a width of 1, and the height of the rectangle I (1≤i≤n) is hi. These n rectangles form a histogram. For example, the height of the six rectangles is 3, 1, 6, 5, 2, 3, respectively.Find the rectangle with the largest area in the given histogram, and its edges

Title DescriptionThe JYY has a rectangle in n plane coordinate systems. The bottom edge of each rectangle is parallel to the x-axis, and the side is parallel to the y-axis. The bottom-left corner coordinates of the I rectangle are (xi,yi), the bottom edge is AI, and the side length is bi. Now Jyy is going to randomly select two different rectangles from these n r
