Generic Tree - Traversals (pre-order, Post-order)

Generic Tree - Traversals (pre-order, Post-order)

Description:
"Traversals in Generic Tree" where we are going to discuss Pre-order and Post-order traversals.
This is a great question to get in depth knowledge on how traversals work which will be beneficial for understanding other questions as well.

Question Name: 
Generic Tree - Traversals (pre-order, Post-order)

Question Link:
https://www.pepcoding.com/resources/online-java-foundation/generic-tree/generic-tree-traversal-official/ojquestion

Question Statement: 
1. You are given a partially written GenericTree class. 
2. You are required to complete the body of traversals function. The function is expected to visit every node. While traversing the function must print following content in different situations.
     2.1. When the control reaches the node for the first time -> "Node Pre" node.data.
     2.2. Before the control leaves for a child node from a node -> "Edge Pre"node.data--child.data.
     2.3. After the control comes back to a node from a child -> "Edge Post" node.data--child.data.
     2.4. When the control is about to leave node, after the children have been visited -> "Node Post" node.data.
3. Input is managed for you.
4. For more detail watch the video.
