Spiral traversal of tree

WebDec 14, 2015 · Here's a simple solution with O(1) space and O(n * h) time, where n is the number of nodes and h is the tree height. Keep two variables pointing to the current levels to print, then print each node after traversing the tree according to a binary string who's length corresponds to the appropriate tree depth; go left for "0", right for "1" (for example, the left … WebGiven a 2-dimensional matrix, write a program to print matrix elements in spiral order. We can imagine spiral traversal as an ordered set of matrix segments with horizontal and vertical boundaries, where both boundaries are reduced by one at each step. Note: This is an excellent problem to learn problem-solving using iteration and recursion.
