Bit Manipulation Interview Questions | Single Number & Subsets | Bit Manipulation Lecture 3

Lecture Resources https://github.com/Tiwarishashwat/Jav... Welcome to Lecture 3 of Bit Manipulation, where we apply all previously learned tricks to solve standard coding interview questions. These problems are frequently asked in interviews and appear across platforms like LeetCode, CodeStudio, and GeeksforGeeks. Topics covered in this video: Find the unique number (all others appear twice) – XOR trick Find the unique number (all others appear thrice) – bit counting approach Find two unique numbers (all others appear twice) Using rightmost set bit to separate numbers Minimum number of bit flips to convert one number to another Generate all subsets (power set) using bitmasking Time complexity analysis for each solution You’ll also understand why each approach works, not just how to code it — which is exactly what interviewers look for. This video is part of my Java + DSA course by ShashCode, designed for: DSA beginners College students Placement & interview preparation Strong problem-solving fundamentals 👉 Watch till the end to master bit manipulation patterns that repeat in interviews.
