Grokking Bit Manipulation For Coding Interviews

Thanks for choosing this course! The techniques you learn here will go towards building strong algorithmic problem-solving skills.

Course Overview

This course teaches bit manipulation, a powerful technique for enhancing algorithmic and problem-solving skills. It is a critical topic for those preparing for coding interviews with 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.

Chapters

1. Getting started: Introductory learning topics about bit-manipulation. Start here to learn the basics.

2. Number Systems, Bitwise, and Binary: Next, you need to understand the number systems in mathematics, like binary, decimal, octal, and hexadecimal. You will be introduced to number representations and mathematical conversions.

3. Bitwise AND: The Bitwise AND operator is denoted by &. When an AND gate is given with 2 inputs, the corresponding outputs will be: If two input bits are 1, then the output is 1. In all other cases, it is 0.

4. Bitwise OR: The Bitwise OR operator is denoted by |. When an OR gate is given with 2 inputs, the corresponding outputs will be: If two input bits are 0, then the output is 0. In all other cases, it is 1.

5. Bitwise NOT: The Bitwise NOT operator evaluates the binary representation of the value of a single input. If the bit contains 1, the output will be 0 for that bit location. If the bit contains 0, the output will be 1.

6. Bitwise XOR: The Bitwise XOR operator is denoted by ^. When an XOR gate is given with 2 inputs, the corresponding outputs will be: If two input bits are different, the output is 1. In all other cases, it is 0.

7. Bit Shifting - Left, Right: A bit shift is a Bitwise operation where the order of a series of bits is moved, either to the left or right, to perform a mathematical operation efficiently.

8. Bitwise Left Shift Problems: Problems on left shift.

9. Bitwise Right Shift Problems: Problems on the right shift.
