这里面包含四个小程序，分别是二叉树染色问题，根据二叉树的先序遍历和中序遍历求出后序遍历，利用队列的保存顺序特性，模拟售票口服务解决实际问题，用递归算法解决分局自问题，这四个程序都是完整的小程序，希望能有帮助。-Here bread containing four small program, are binary tree coloring problem, according to the postorder traversal of binary tree preorder traversal and traversal in order to calculate, the queue order preserving properties, simulated wicket service to solve practical problems, the branch since the problem, the four procedures are complete program solve with recursive algorithm, hope can help.
