Challenge 1: Count Set Bits Or Number of 1 bit's

This is a traditional problem counting the number of set bits or 1's present in a number. Let’s see how we can count the set bits using the AND operator.

Bitwise AND, Computations, and Examples

A Bitwise AND is a binary operation that takes two equal-length binary representations and performs the logical AND operation on each pair of the corresponding bits. This is equivalent to multiplying them.

Introduction to Bitwise AND operator

Bitwise AND is the most commonly used logical Bitwise operator. It is represented by a sign (&). AND operator is the same as the AND gate we studied in the chapter on digital electronics.

Convert Decimal Numbers to Binary Numbers

We use the modulo and division method, and we calculate the binary representation of a decimal number. Let’s represent the binary by considering the remainder column from bottom to top.

Binary Number System and Its Representation

In mathematics and digital electronics, a binary number is expressed in the base-2 number system, using only two symbols: "0" and "1". Another number system that became famous after the decimal is the binary number system, which has only two digits, 0 and 1.

What is Decimal Number System?

Long ago, humans created a number system that has precisely ten digits. This number system is called the Decimal Number System, and the digits in this number system are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Introduction to Number Systems

A number system is a writing system where digits and symbols are used in a consistent manner to represent values. The exact sequence of symbols may represent different numbers in different number systems.

What is Bit Manipulation?

Bit manipulation is algorithmically manipulating bits or other pieces of data shorter than a word. Bit manipulation is something that has constant time complexity.
