Hello guys,
Currently I am writing about Bit Masking on my blog. Today I have published first part of this series.
I have covered following topics in first part :

Introduction to Bit Manipulation

Applications of Bit Manipulation

Basic Introduction to Bit Masking

Solving subset sum problem
Here is the link to first part : Introduction to Bit Masking
Edit : I have published second part of Bit Masking + dynamic programming tutorials. I have solved a problem using
Bit Masking and DP and also showed how it makes implementation easier.
Here is the link to second part : Bit Masking + Dp Part 1
Thank you and Happy Coding!
