Question
I need help in writting this in c++ code
how can we implemnted a post order transveral to construct this binary tree while reading the infomation displayed on the text file?

Transcribed Image Text: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. For example, this file will make the following tree:
root
2
15
