To protect people from evil, a long and tall wall was constructed a few years ago. But just a
wall is not safe, there should also be soldiers on it, always keeping vigil. The wall is very
long and connects the left and the right towers. There are exactly N spots (numbered 1 to
N) on the wall for soldiers. The Kh spot is K miles far from the left tower and (N+1-K) miles
from the right tower. Given a permutation of spots P of {1, 2, .., N}, soldiers occupy the N
spots in that order. The PIth spot is occupied before the Pli+1) spot. When a soldier
occupies a spot, he is connected to his nearest soldier already placed to his left. If there is
no soldier to his left, he is connected to the left tower. The same is the case with right side.
A connection between two spots requires a wire of length equal to the distance between the
two. The realm has already purchased a wire of M miles long from Nokia, possibly the wire
will be cut into smaller length wires. As we can observe, the total length of the used wire
depends on the permutation of the spots P. Help the realm in minimizing the length of the
unused wire. If there is not enough wire, output -1.
