Interpreting I know of at least sign language the state is requiring you to be certified in order to have that occupation.
Answer:
Let L and R be the sub-trees underneath the root r.
If the height of L (where we consider height to be the maximum length of all root-leaf paths) is ∆ more than that of R, ∆ ≥ 0, then the length of the edge (r, R) is increased by ∆.
Then, we separately perform the same cycle over L and R.
Once more, by induction, argue that this greedy algorithm is efficient –
when it does not increase the length of (r, R) edge by ∆, then prove that the solution can be improved.
I don't think it has an option to change your country. If you'd like to see things in a different language, that's probably a different story.
