Binary Search Tree (BST)
Definition
The value of left child is smaller than the root node, and the value of right child is greater than the heel node. The value of left child and right child also meet the preceding conditions.
Suppose there are three nodes, and there are a total of five possible BST:
1 3 3 2 1 \ / / / \ 3 2 1 1 3 2 / / \ 2 1

Define the formula $ J (x) = \ sum _ {1 \ Leq k \ Leq X and k | X and \ gcd (K, X/K) = 1} k $.
Given an integer $ A $, the number of positive integers $ x $ must be equal to $ J (x) = A $.
$ X | N $ indicates that $ x $ is a factor of $ N $.
$ \ Gcd (a, B) indicates the maximum common divisor of $ A $ and $ B $.
