__Depth of a node__

The depth of a node A in a binary tree is the length of
the unique path (number of edges) from the root of the tree to the node A.

The root node is at the depth 0.

**Example:**

Depth of node K – 3 [

*edge AB (e1), edge BF (e4), and edge FK (e7)*]
Depth of node I – 2 [

*edge AD (e2), and edge DI (e5)*]
Depth of node J – 2 [

Depth of node A – 0 [*edge AD (e2), and edge DJ (e6)*]*root node*]
