Binary Tree Traversal

Depth First Traversal:
Approach: Stack
Traverse the tree from root to node, check if each node has a child, and add them. After every iteration, check if the node has a child node. Pop the elements of the stack and continue iterating until you reach the end.
Result: a,c,f,b,e,d

Breadth First Traversal:
Approach: Queue
Add each node and child node to the queue, in a sequential order. Pop the first item of the queue, print it and append if it has any child nodes. Continue this process till the end.
Result: a,b,c,d,e,f

Space complexity: O(n)
Time complexity: O(n)
