Problem 1 OO solution code has been updated and continues to accelerate.

I posted a solution to the second question yesterday. You gave me a lot of comments and gained a lot. Continue to issue the first question today. We can see that everyone is using OO to solve the problem, but Oo should not be slower, right ..

For more information, seeAlgorithm.

With the OO design concept,CodeIf there are too many files, you don't need to paste them. Package and download/files/Pandora/t1_oo_fast.zip (add the comparison test code)

I don't know whether Oo is complete or not. I am doing it all by feeling. Let's give more comments.

First algorithm question (250 points)

It is said that when you walk to work, you pass through a farmland where radishes are planted. The shape of this field is a rectangular grid. The J-character of the I-th element of field indicates the number of radishes contained in the grid in column J of the I-th row of the field. We define a lattice as the sum of the numbers of radishes in all its surrounding grids. The grids around it include the upper, lower, left, and diagonal adjacent grids, with a maximum of eight, there will be fewer grids on the boundary of the field. If there is no grid around a grid, it is special to 0.
Return the number of all grids (including a and B) between A and B in a field to a particular extent ).
