When we have two tree walks, they generate a unique tree. Suppose we traversed a tree T for an in-order tree walk and a post-order tree walk as follows; In order tree walk of tree T = {15, 28, 35, 38, 40, 45, 55, 60} Post order tree walk of tree T = {15, 40, 38, 45, 35, 28, 60, 55} What is the height of the tree T?
