Fast diameter of tree question

[mittali (mittali goyal)]

In this, its taken a pair class for (H,D), but for the overall question we only need diameter. we can also make a function which return only int of D. and ofcourse diameter will be always greater then height. so we can do max of (h,d) and return that?

@mittali

we can do max of (h,d)

but to calculate current node height we also need height of left and right subtree
