Given a binary tree, flatten it to a linked list in-place.
For example,
Given
1 / 2 5 / \ 3 4 6
The flattened tree shoshould look like:
1 2 3 4 5 6
Idea: This question is essentially a first-order traversal of a binary tree. Let's first look at the recursive solution. The function flattensub (node) processes the tree with node as
