The ultimate guide to bit manipulation for coding interviews. Developed by FAANG engineers, practice with real-world interview questions, and get interview-ready in just a few hours.

This course teaches bit manipulation, a powerful technique to enhance algorithmic and problem-solving skills. It is a critical topic for those preparing for coding interviews for top tech companies, startups and industry leaders. Competitive programmers can take full advantage of this course by running most of the bit-related problems in O(1) complexity.

The course will begin by educating you about the number system and its representation, decimal and binary, followed by the six bitwise operators: AND, OR, NOT, XOR, and bit-shifting (left, right).

You will receive ample practical experience working through practice problems to improve your comprehension.

Upon completing this course, you will be able to solve problems with greater efficiency and speed.

Grokking Bit Manipulation for Coding Interviews

This course has taught you how to re-write arithmetic operators like `+, -, /, *` into left, right shift, and other bit-level operations.

We hope that the learning you gained in this course will be useful in solving Leetcode, Hackerrank, HackerEarth, Codeforces, Codechef, and other online coding challenges. This will also help you with interviews at FAANG or other top tech companies. We wish you good luck and hope this course makes a difference in your coding journey!

> **Note:** I will also implement solutions in Rust and Go in upcoming edits.

This concludes our course on bit manipulation.
