What is Bitwise Algorithms?
Bitwise algorithms refer to algorithms that perform operations on individual bits or bit patterns within computer data. These algorithms uses the binary representation of data and use the fundamental bitwise operations such as AND, OR, XOR, NOT, and bit shifting to manipulate and extract information from the data.
Bitwise algorithms are usually faster and use less memory than regular arithmetic operations because they work directly with the binary representation of data. This often leads to faster execution times and reduced memory usage.
Introduction to Bitwise Algorithms – Data Structures and Algorithms Tutorial
Bit stands for binary digit. A bit is the basic unit of information and can only have one of two possible values that is 0 or 1. In our world, we usually with numbers using the decimal base. In other words. we use the digit 0 to 9 However, there are other number representations that can be quite useful such as the binary number systems.
Unlike humans, computers have no concepts of words and numbers. They receive data encoded at the lowest level as a series of zeros and ones (0 and 1). These are called bits, and they are the basis for all the commands they receive. We’ll begin by learning about bits and then explore a few algorithms for manipulating bits. We’ll then explore a few algorithms for manipulating bits. The tutorial is meant to be an introduction to bit algorithms for programmers.
