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.
