[System Security 16] Optimization principles of addition and subtraction, multiplication and division
0x1 Optimization principle of addition and subtraction 1.1 Identification and Optimization of Addition There are three options for additive optimization: 1) Form 1: Variables and variables 2) Form 2: variable plus constant 3) Form 3: Variable plus 1 C source code: int _tmain(int argc, _TCHAR* argv[]) { int nNum, nA = 8; nNum = argc […]
ZJNU 2770 – MRAVOJED (prefix sum + binary division + bit operation)
Description In a gray and white picture of \(n\times m\), it is required to calculate how many gray grids have been traveled in the previous \(k\) steps. See the picture on the right for the method of movement. Define the upper left coordinate as \((0,0)\) and the lower right coordinate as \((n-1,m-1)\). For the grid […]
Fractional addition, subtraction, multiplication, division, power, and polynomial processing of brackets based on C++
Introduction In this article, we will explore a C++ program that can evaluate mathematical expressions involving fractions and power operations. First, we’ll simplify and perform basic fraction operations (addition, subtraction, multiplication, and division) with a series of powerful functions. We then show how to use these functions and Step 1: Define the fraction operation function […]
Linux is just a non-real-time system based on time slice division
Link: https://www.cnblogs.com/xiawen/p/3317302.html Everyone who plays microcontrollers is basically very familiar with operating systems such as μC/OS, FreeRTOS, and ThreadX. They are all real-time operating systems (RTOS) and are widely used in the industrial field; however, for non-real-time systems based on time slice division like Linux, It is difficult to meet the real-time requirements, but currently […]

Five methods of Vue to implement addition, subtraction, multiplication and division operations
Detailed description of the five methods: Computed Properties: Computed properties are a convenient property provided by Vue.js, which dynamically calculate a new value based on dependent data. The value of a computed property is cached and is recalculated only when the dependent data changes. Computed properties can be used directly in templates just like ordinary […]
