Currently, there are two kinds of numerical schemes for computing the ZRP automatically with computer programs: one is based on the definition in which the factorial operations may lead to the overflow problem and the high order derivatives are troublesome, and the other is based on recursion ...

下面是Bottom-top的方法。从最底层的节点开始比较,一旦出现不平衡节点就返回负值,如果到最后都没有返回负值,则整棵树平衡。这个方法的复杂度为O(N)。 # Definition for a binary tree node.# class TreeNode(object):# def __init__(self, x):# self.val = x# self.left = None# self.right = None...
