Computer algorithm design and analysis (Chapter II computer practice)
7-1) binary search
Enter n values (1 < = n < = 1000), n integers in non descending order and the number x to be found. Use the binary search algorithm to find x, and output the subscript (0~n-1) where x is located and the number of comparisons. If X does not exist, output - 1 and the number of comparisons.

Introduction to OpenCV -- image smoothing technology
About image sampling
There are many ways to obtain digital images. Usually, image sampling can be used to digitize continuous images. The collection relationship between sampling points is the grid, and the infinitesimal sampling points between grids correspond to the pixels in the image. Sampling on image transformation is the process of cha ...

1. Why modular programming?
A: if I were Party A, I would put forward my requirements to you. After a month, you finally wrote the code I wanted. However, if you write all the functions in a c file, do you think I will ask you for later maintenance? Impossible, because I understand your whole program framework, I will main ...

Syntax: Type & reference variable name (object name) = reference entity;
For example, if a pe ...

GAMES101 - computer graphics - Assignment 5
1 Overview In this part of the course, we will focus on rendering images using ray tracing. One of the most important operations in ray tracing is to find the intersection of light and object. Once the intersection of the light and the object is found, you can perform shading and return the pixel color. In this assignment, we need to realize tw ...
