CodeChefRating 2437Open on judge ↗

El Macho's army of mutated minions is marching towards Gru, the army is standing in a rectangular formation measuring NxM. The spray of antidotes done by Gru has turned some of the minions back to normal, but now they are trapped within the army of mutated ones. Formally, a normal minion is "not trapped" if : 1) either he is on one of the edges of the rectangle 2) or one of his direct neighbors
