Stacking cubes with different weights and colors on each side, being put in a way so that
- Any lower cube has more weight than the upper one
- Any lower cube has the same color on top side as the bottom side of upper one
Depict all possibilities in a given chess board containing obstacles which
N
queens can safely stand. Note that obstacles can prevent queen's threat in any way the queen can threat other pieces.
Given any house of the chess board is scored with an intger between 1 to 64, find certain states of board containing
N
queens, in which sum of house scores having queens on them be above a given number likex
. Try to design the algorithm in an optimized way.
