Tutorial: SquareRoot Decomposition + Dynamic Programming

Hi everybody,

I recently solved an interesting problem based on matrices, math, data structures and dp.
I made a YouTube Video in 2 parts for it.
The 1st video talks about the problem and approaching the solution.
The 2nd video talks about the squareroot decomposition part.
To read more about it, go to this link on my blog.

I hope you guys will like it!
