Submatrix Sum Querry (content 5/8)

In this lecture, I was able to understand the Prefix Sum Matrix Method but I was not able to implement the code.

May you please send the code of the above lecture, so that I can understand the implementation of this lecture.

If possible, Please try to provide the code in IDE of Coding Blocks.

Thank You
