Dp [I] [j] indicates the total number of possible rectangles with a length and width of I. j.
Dp [I] [j + 1] can be pushed by dp [I] [j] to enumerate the number of rows retained by dp [I] [j] (1... I ).

Dp [I] [j] indicates the number of matrix schemes of I ipvj. dp [I] [j] is transferred from dp [I −k] [j −1, if k behavior is null in the J-1 column before enumeration, these rows must have a gem in column j.

Problem descriptionOne day, Harry got a magical box. The box is made up of n*m, and there are some glittering gems in the lattice. But the top and bottom of the box were sealed with magical magic, so Harry couldn't see the inside of the box from the top and bottom. However, the four sides of the box are transparent, and Harry can see the situation from the sides of the box.
