High-precision subtraction (implemented in C language)
High-precision subtraction (implemented in C language) Introduction As we all know, integers are stored in three different sizes of data in C and C++: int, long, and long long. The maximum data size can be Up to 2^64, but in actual use, we will inevitably encounter extremely large number operations that explode long long. At […]

[ABC278G] Generalized Subtraction Game
Problem Statement This is an interactive task (where your program interacts with the judge’s program via Standard Input and Output). You are given integers $N$, $L$, and $R$. You play the following game against the judge: There are $N$ cards numbered $1$ through $N$ on the table. The players alternately perform the following operation: choose […]
Traditional moving target detection algorithms-frame difference method, optical flow method, background subtraction method
1. Moving target detection Motion Object Detection is an important task in the field of computer vision and image processing, aiming to detect and track moving target objects from videos or image sequences. These target objects can be people, vehicles, animals or other objects, and the goal of moving target detection is to accurately locate, […]
Edabit Algorithm Fractions Addition And SubtractionFractions Addition And Subtraction
Fractions Addition And Subtraction simulation recursive Instructions The function is given a string representing an expression of many fractions addition and subtraction. Compute the arithmetic result and return the string in the form of an irreducible fraction. Even if the result is an integer, e.g. 3, return it as 3/1. Examples fractionsAddition(“4/5-6/4”) // “-7/10” fractionsAddition(“5/4-6/6”) […]
Matrix operations (addition, subtraction, multiplication)
Define three methods Add, Sub, and Mul to complete operations on matrices. Addition is similar to Subtraction, except that the operations performed during the loop are different. Multiplication is more complicated than the above two operations. For example, the two matrices are 2×3 and 3×4 matrices (in order to do matrix multiplication, the order of […]
Use opencv to combine frame difference method and background subtraction to detect scene anomalies
1. Frame difference method to detect abnormalities Frame subtraction is a simple background subtraction technique used to detect the difference between the current frame and the background frame. The following is an example of Python code using OpenCV to implement the frame difference method: import cv2 # Read the background image (the background should be […]
verilog implements IEEE754 half-precision floating point number addition and subtraction operations
1. IEEE754 protocol half-precision floating point number format and conversion Format: The binary half-precision floating point number has a total of 16 bits, and the index is 0-15. The 15th bit is the sign bit, 0 represents positive and 1 represents negative, 14-10 bits are the exponent code, and 9-0 bits are the mantissa bit. […]
XDOJ-276 Data Structure-Polynomial Addition and Subtraction
As a one-star question in xdoj, I really didn’t expect this question to be so troublesome when I first started doing it (mainly because the question was so long that I didn’t have the desire to read it carefully. As a result, I discovered the hidden reason later, so I said Be sure to read […]
