Bitwise

Ever wondered where those zeros and ones that computers supposedly work with are actually located? While you’re writing code in high-level programming languages, the system quietly manipulates these binary digits behind the scenes. Understanding bit manipulation can make your programs very, very fast – and that’s exactly why tech companies love engineers who master these concepts. What Are Bits and Why Should You Care? A bit is the smallest form of memory that can be occupied in a computer. Simply put, it’s either set (1) or not set (0) – …

Let us suppose you are given an array of integers. The special thing about this array is that all numbers are repeated twice except one. Find the single non-repeating number. Example 1:Input: [2, 1, 1]Output: 2 Example 2:Input: [4, 5, 5, 2, 2]Output: 4 Problem statement: You are given an array of all positive integers. All the integers are repeated exactly twice except one. We need to find that number with a linear time complexity and using the minimum space possible. Brute Force Method: When tackling such problems, it is …
