There seems to be an inconsistency in the “Diameter of Binary Tree” examples.

For:
root = [1,null,2]

the output is shown as:
2

which counts the diameter in terms of nodes.

But for:
root = [1,2,3,null,null,4]

the output is shown as:
3

which counts the diameter in terms of edges.

Diameter should be measured consistently using either:

• number of edges
  or
• number of nodes

Under the standard definition (edges), the first example should return:
1

not 2.
