Binary tree traversal has used three methods, namely: first, the root sequence, the order of the root, root, after the order. In order to verify the difference between these types of traversal algorithm, this experiment will achieve all of the algorithms. Through time, to print out the information nodes, node information to make it easier for the difference, with each node before the digital ID. Such as: data [1] = A, data [2] = B. The algorithms are all recursive algorithm to achieve
