Mr. Moled has n column reservoirs underground, numbered from 1 to n. All of these reservoirs have a same sectional area. To connect these reservoirs, Mr. Moled digs m pipes. Each pipe connects exactly two reservoirs. And all the pipes are parallel with the ground. These pipes are so thin that they will not save any water. Now Mr. Moled will pour water into the reservoirs. You can assume the water passes through the pipes very quickly. Mr. Moled wants to know the height of the water in each reservoir at last.
