[Source of the question]http://acm.hdu.edu.cn/showproblem.php?pid=1686http://poj.org/problem?id=3461 [Title description] The French author Georges Perec (1936–1982) once wrote a book, La disparition, without the letter ‘e’. He was a member of the Oulipo group. A quote from the book: Tout avait Pair normal, mais tout s’affirmait faux. Tout avait Fair normal, d’abord, puis surgissait l’inhumain, l’affolant. son tapis, assailant […]
Tag: overlapping
The overlapping and stacking of echarts’ histogram realizes the display of two bars and the previous difference display.
renderings Main idea Prepare three cylinders (original plan, actual progress, difference) The original plan and actual progress are set to overlap {<!– –> barWidth: 20, // yAxisIndex: 1, z: 1, name: ‘original plan’, type: ‘bar’, stack: ‘ab’, emphasis: {<!– –> // Click on the cylinder and the color of other cylinders will become lighter. disabled: […]
Qt desktop whiteboard tool part 2 (implementation method of highlighter and solving the problem of overlapping dark spots caused by transparency)
Previous article: One of the Qt desktop whiteboard tools (solve the problem of uneven curves – Bezier curve) 1. Foreword: I’m quite talkative and may talk a lot of nonsense. In the previous article, I mainly shared about the problem of non-smooth curves solved by the Bessel algorithm. Simply put, we can use the algorithm […]
Heap utilization-Chunk extend Overlapping
Vulnerability Introduction chunk extend Overlapping is a relatively common method of utilization in the heap. The main principle is that we can modify the size of some heap blocks that have been applied for or are in the idle state due to some unexpected situations, resulting in overlapping heap blocks, which is also It caused […]
OpenStack (4)–NameSpace realizes overlapping network segments of different projects (tenants)
Openstack isolates the networks of different projects (tenants) through namespaces. The administrator of each project needs to plan and construct the project network, which leads to the reuse of certain network segments between different projects. For example, 192.168.X.X is the management The network segment used by the staff. Last time we created a new instance […]

Article directory Circle and Rectangle Overlapping Whether the circle and rectangle overlap Problem Description: analyze the code tag Circle and Rectangle Overlapping Whether the circle and rectangle overlap Description of problem: Given a circle represented by (radius, xCenter, yCenter) and a rectangle parallel to the coordinate axes ( x 1 x_1 x1?, the y 1 […]
Network programming–realize echo server in pure overlapping IO mode
Write in front The overlapped IO model only introduces the Sender and receiver that perform overlapped IO, but the echo server has not been implemented using this model. Therefore, this article will implement an echo server based on the overlapped IO model on this basis. ioctlsocket The ioctlsocket function is used to create a socket […]
Network programming–overlapping IO model
Write in front The asynchronous notification IO model introduced in the article Asynchronous notification IO model belongs to the notification IO model, and the IO multiplexing described in the similar select implementation of IO multiplexing also belongs to the communication IO model. What is the notification IO model, that is, the IO is completed to […]
