The binary list validation binary tree the preorder achieve CreateBiTree algorithms to create a binary tree, the binary tree hierarchy traversal algorithm to achieve binary tree inorder, postorder recursive traversal algorithm write main program to call CreateBiTree create binary tree, and call the level traversal of a binary tree, the first (in the rear) preorder traversal algorithm, to test different input data to create a binary tree, it is expected that the output and verify that the output results.
