Gorgeous Space Station

Limits: 1s, 1.0 GB

Doro is the chief commanding officer of two space stations, Mungi and Hanzi. To make both stations gorgeous, he has decided to change the color of both stations. He has rented the robot Bingo to do this job. Since everything in space is too costly, using Bingo is costly too. The cost of Bingo depends on the amount of time it works. In each second Bingo can either color 1 meter2 area or fly 1 meter. Bingo always flies in a straight line.
