Discussion of Problem 1017. Staircases

I think it in this way.

Considering that d[i][j] indicate the number of i bricks divided into j columns steps.So if we cut away the downmost brick of every steps, and we can get d[i][j] = d[i-j][j-1](if the 1st step only have one brick) + d[i-j][j](if the 1st step have more than one brick).
Thus q = d[n][2->max_j]
