Master chain and sequential storage structure of the binary tree using a queue to operate the binary tree. Experimental content: 1) write function creatbt, its function is one-dimensional array stored binary tree into a chain store binary tree to return to the root pointer. 2) write functions freebt, and its function is to release binary tree list node storage space. The function prototype: void freebt (TNODE* root) 3) write functions preorder, inorder and postorder traversal
