Bit Manipulation Coding Questions for Interviews Last Updated : 22 Sep, 2025 Comments Improve Suggest changes 4 Likes Like Report Common bitwise operators like AND, OR, XOR, and NOT allow you to manipulate individual bits within integers, providing a powerful toolkit for solving problems such as detecting duplicates, counting set bits, or performing arithmetic operations efficiently. Whether it's finding the missing number in a sequence or optimizing space in data structures, bit manipulation techniques can significantly improve your problem-solving approach in coding interviews.Easy ProblemsBinary Representation Turn off the rightmost set bit Check if K-th Bit Set Set the K-th Bit Modulus division by 2's Power Odd Occurring NumberPower of twoThe only set bit Add Bit StringsCheck for Integer OverflowXOR without using XOR Check for EqualCheck for opposite signsSwap Two Numbers Russian Peasant Medium Problems Most Significant Set Bit Rightmost Set BitCount Set Bits Swap Bits Rotate Bits Smallest of Three Minimum without branchingSmallest power of 2 greater than or equal to nProgram to find parityCheck if binary is palindromeGenerate n-bit Gray CodesCheck for SparseEuclid when % and / are costlySquare without using *, / and pow()Cyclic Redundancy Check and Modulo-2 DivisionSet Bits in a RangeCheck for BleakGray to Binary and Vice Versa Hard ProblemsNext higher with same set bitsKaratsuba Algorithm for fast MultiplicationMax Subarray XORLongest Sequence of 1’s in Binary with One FlipClosest Smaller and greater with same set bits Bitmasking and Dynamic Programming Compute the ParityXOR Encryption by Shifting PlaintextCount pairs with at least one digit commonFloating to BinaryBooth’s Multiplication AlgorithmPairs with Pandigital Concatenationn-th number whose binary is a palindromeTwo non-repeating in an array of repeating Related Links DSA TutorialSystem Design Tutorial GfG 160DSA 360° Create Quiz Comment U ujjwalroq0 Follow 4 Improve U ujjwalroq0 Follow 4 Improve Article Tags : Bit Magic DSA Explore DSA FundamentalsLogic Building Problems 2 min read Analysis of Algorithms 1 min read Data StructuresArray Data Structure 3 min read String in Data Structure 2 min read Hashing in Data Structure 2 min read Linked List Data Structure 3 min read Stack Data Structure 2 min read Queue Data Structure 2 min read Tree Data Structure 2 min read Graph Data Structure 3 min read Trie Data Structure 15+ min read AlgorithmsSearching Algorithms 2 min read Sorting Algorithms 3 min read Introduction to Recursion 15 min read Greedy Algorithms 3 min read Graph Algorithms 3 min read Dynamic Programming or DP 3 min read Bitwise Algorithms 4 min read AdvancedSegment Tree 2 min read Binary Indexed Tree or Fenwick Tree 15 min read Square Root (Sqrt) Decomposition Algorithm 15+ min read Binary Lifting 15+ min read Geometry 2 min read Interview PreparationInterview Corner 3 min read GfG160 3 min read Practice ProblemGeeksforGeeks Practice - Leading Online Coding Platform 1 min read Problem of The Day - Develop the Habit of Coding 5 min read Like
