WebMar 6, 2015 · Iterative Way: For a spiral traversal, we can start from the root and iterate till the height of the tree. Each iteration must print one level of the tree and hence the number of iterations would be equal to the height of the tree. We need to be careful to cautiously swap teh order of printing/visiting every alternate level. sacks exhibits woburn
