Read from 'Rooms.txt' the binary tree structure of the Rooms and the number of Robots in each Room. For each Room, the name is on one line, followed by number of children, number of Robots, and an empty line. Each Room entry will be the leftmost available child starting from the root; by the end of the file, there should be no leaves with children > 0.
