One, design ideas:The goal of this implementation is to implement the user input answer on the basis of the previous code, and to determine whether the answer is correct and statistics, and then output the correct number of answers.The idea of judging whether the answer is correct is to define wrong (to count the number of errors) on the previous basis, K1, parameters.In the void display function, we define the judgment of the answer and the statistic

does not satisfy the equilibrium property after the node operation is deleted, and its right subtree depth is greater than the depth of the left sub-tree. i.e. (Depth (r)-depth (l) = = 2)
The deleted node is on the right subtree of the left subtree of T. This is where we use the right single rotation to balance it.
Each of these two methods has a symmetric situation, which is solved by using the left rotation.
I'll write the method of rotation first:

It seems this problem is about enumeration of combination.
Using DP.
If I had already get F (n-1), means in total n-1 units, there are f (n-1) kinds of beautiful arrangements.
Suppose the beautiful arrangement is xxxxxxxxxxxx, X means unit, then put a new unit on the right will form a new arrangement.
Let f means fooman unit, H means horseman unit. And k1 = 3, K2 = 5
