Time Complexity Visit each node three times O(n) first arrival return from left child return from right child Time and Space Complexityfor Depth-First Search Algs.
Space Complexity Stack to handle recursion Stack length = depth of tree best case: lg n worst case: n O(n) Time and Space Complexityfor Depth-First Search Algs.
