1. DefinitionThe basic operation of a direct insert sort (straight insertion sort) is to insert a record into an ordered table that is already sorted, resulting in a new, sequential table with a 1 increase in the number of records.The basic idea of inserting a sort (insertion sort) is to insert a record to be sorted each time, by its keyword size, into the appropriate location in the previously sorted sub-file until all records are inserted.2.

This article mainly introduces Python's method of determining whether a straight line and a rectangle are intersecting. It involves the calculation of the line and a rectangle in the Python coordinate system and has some reference value, for more information about how to determine the intersection of a straight line and a rectangle in Python, see the following example. Share it with you for your reference.

original article, reprint please indicate from Iron Man Mac blog http://www.cnblogs.com/gangtiexia The basic idea of a direct insert sort (straight insertion sort) is to insert a new record into an ordered table that is already sorted, that the initial ordered table has only the first data of the unordered table, and sequentially inserts each data into the unordered table in order to get an ordered table , the specific steps are If new record

Basic idea:Insert a record into the sorted ordered table to get a new, sequential table with a 1 increase in the number of records. That is, the 1th record of the sequence is considered to be an ordered subsequence, and then inserted from the 2nd record one after the other into the entry until the entire sequence is ordered.Important: Set up Sentinel as a temporary storage and judgment array boundary.Example of a direct insert sort:If you encounter an element equal to the insert, the insertion e

simplest: Straight Line The method for drawing a straight line is lineTo. Its parameters are the same as those of moveTo, and they are all points. Ctx. lineTo (x, y) Of course, when you draw a line, the pen points also move, so after lineTo, the pen point becomes his target point. The Code is as follows: Ctx. moveTo (100,100 );Ctx. lineTo (200,100 ); When you refresh the page, you will find that ther

ObjectiveIn mathematics, the ideal line is no width, it is a collection of countless points. When a line is rasterized, it is only possible to determine the best approximation of a set of pixels in a given, finite number of pixels in a matrix, and to scan the line order.This section describes three common algorithms for plotting lines with a line width of one pixel: numerical differentiation , midpoint drawing lines , and Bresenham algorithms .Numerical differential methodThe

Question: give n straight lines, divide a plane into multiple parts, and then give m the coordinates of the server guard. In one part, only one server guard can protect this part, ask if the M server guard provided protects all parts. Solution: Calculate the positional relationship between each server guard and each line (above or below), expressed in, so each server guard has a 01 string, finally, the number of parts divided into the n

IOS 2D plotting (Quartz 2D) path (point, straight line, dotted line, curve, arc, elliptical, rectangle) A path can contain one or more shapes and subpaths. quartz provides many convenient shapes that can be called directly. For example, point, line, Arc, Curves, Ellipse, and Rectangle ). You can perform stroke or fill on these paths, or use path to intercept a region (clip ). For example, you can intercept a circular area. If you still have no ide
