Let’s say, we have two variables, A and B, and our task is swapping these two variables without extra space. First, we can this: A = A + B and, B = A – B = A + B – B = A (import A from Step 1) finally, A = A – B = A + B – A = B (import A, B from...
Here, we will see all the preferable examples that will make the swap task more flexible. Let’s hop into the codebases! Use Temporary Variable to Swap Array Elements in JavaScript In the following example, we will take two arrays with corresponding elements. Our target here is to assign a...
Suppose you have two variables x and y and you want to swap their values. The usual way to do this is using another temporary variable: temp = x; x = y; y = temp; However, the interchange of two variables can be done without the temp variable: x = x + y; y = x - y; x ...
In this method, a temporary variable is used to swap two values. Consider two variables, a and b and a temporary variable, temp. First, the value of a will be copied to temp. Then the value of b will be assigned to a. Lastly, the value of temp will be assigned to b, and the ...

C program to swap two integer numbers without using temporary variable: Here, we will learn how to swap numbers without taking help of another variable in C? Problem statementGiven two integer numbers "a" and "b" and we have to swap their values without using any temporary variable....
This chapter is a basic tour of the kernel-provided device infrastructure in a functioning Linux system. 本章是对Linux系统中内核提供的设备基础架构的基本介绍。 Throughout the history of Linux, there have been many changes to how the kernel presents devices to the user. We’ll begin by looking...
In other words, you’ll learn how the kernel moves into memory up to the point where the first user process starts. 你现在已经了解了Linux系统的物理和逻辑结构,知道了内核是什么,以及如何处理进程。 本章将教你内核是如何启动的。换句话说,你将学习内核如何将自己加载到内存中,直到第一个用户进程开始...
