For the below example tree, all root-to-leaf paths are:
10 –> 8 –> 3
10 –> 8 –> 5
10 –> 2 –> 2
Use a path array path to store current root to leaf path. Traverse from root to all leaves in top-down fashion. While traversing, store data of all nodes in current path in array path. When we reach a leaf node, print the path array.
10 8 3 10 8 5 10 2 2
Time Complexity: O(n2) where n is number of nodes.
