Given a wall of L*W size. The wall is made up of bricks of sizes 1*1. We need to color the wall with K(given) colors such that no two adjacent bricks (bricks sharing a side) get the same coloring. How many ways to do achieve that? constraint: K, L and W are in the range of 100000.
-- how to approach this QS? Simple dynamic programming (states as position and check all colors etc.) is not feasible with given constraint. Thanks!
