The depth-first search (DFS) is a tree traversal technique. In DFS, we go as deep as possible down to one path before we explore or visit the different node or the next sibling (It’s like a maze; you go to one end before exploring other side). Here is how the depth-first search...

If I understand the exercise correctly, you would have to come up with formulas for how to calculate the label of the left and right child during each method of traversal, given the label of the current node and the depth. For example, during pre-order traversal, the ...
