Count set bits in an integer
Introduction In this article, we will address the problem of "Counting set bits" or, alternatively, "Counting the number of set bits in an integer". Our approach will begin with a comprehensive understanding of the problem, followed by a brute-force solution, and eventually optimizing it with logical thinking. We hope this problem-solving journey will help boost your critical thinking and programming abilities. Without further ado, let's begin. Contents [ hide ] Understand the question The question "Count set bits in an integer" is asking for the number of 1s or set bits in the binary representation of a given integer. The binary representation of an integer is a sequence of 0s and 1s that represent the number in base 2. For example, the decimal number 7 is represented in binary as 111, which has three set bits. Similarly, the decimal number 10 is represented in binary as 1010, which has two set bits. The task is to coun...
