Binary Tree Example [In Order Traversal] - Written in Java.
Visualization of the binary tree
.30.
25_/ \_50
20_/ \_72
7_/ \_21 \_1337
So effectively what my program does,
Is traverse the binary tree, in order [ left node > root node > right node ],
The output should show: "7 20 21 25 30 50 72 1337" - if it completes successfully.
