Byte-Sized-Chunks: Bit Manipulation Problems from Udemy

Note: This course is a subset of our 20+ hour course 'Break Away: Programming Interviews' so please don't sign up for both:-)

Programming interviews are like standard plays in professional sport - and bit manipulation questions are very common in certain types of interviews.

This course has been drawn by a team that has conducted hundreds of technical interviews at Google and Flipkart

Bit manipulation problems are an interview favorite, and they also pop up in some real-word programming cases, particularly low-level or very computationally intensive tasks.

What's covered:

The bitwise AND, OR, NOT operators: Visually understand exactly how the bitwise AND, OR and NOT operators work

Bitwise Shifting - Overflow and Fill: The bitwise shift operators can be quite tricky - we cover these in some detail

Bit Manipulation - get and set a specific bit

Counting Set Bits with a nifty trick to do so in time complexity O(# of 1s)

Reverse Bits in a number

Bit Manipulation Problems

You, This Course, and Us!

We dig into the bitwise AND, OR and NOT operations - visually inspecting how they work.

We continue with bit manipulation - the right shift and left shift operators are very powerful, but they have 2 issues that you should be sure to understand: overflow, and fill.

Functions to get the nth bit of an integer and to set the nth bit of an integer. These are the building block functions and the concepts underlying these will be used for harder bit manipulation problems.

Print all the bits used to represent an integer from the most significant bit to the least significant. Learn some subtle details about the shift right (>>) with negative numbers!

Count the number of 1s in an integer, and learn a neat trick which allows you to do it in complexity O(number of 1s).
