第二种解法还可以再优化下,将递归方法内置,同时min初始值为int类型的最大值,而不是第二种解法的0,可以省去一步判断。 Integerprev2=null;intmin2=Integer.MAX_VALUE;publicintgetMinimumDifference3(TreeNode root){if(root ==null) {returnmin2; } getMinimumDifference3(root.left);if(prev2 !=null) { ...
Explanation: The minimum absolute difference is 1, which is the difference between 2 and 1 (or between 2 and 3). Note: There are at least two nodes in this BST. 题意及分析:给出一颗二叉搜索树(节点为非负),要求求出任意两个点之间差值绝对值的最小值。题目简单,直接中序遍历二叉树,得到一个...
public int getMinimumDifference(TreeNode root) { inOrder(root); return minDiff; } public void inOrder(TreeNode root){ if(root == null){ return; } inOrder(root.left); if(prev !=null) minDiff= Math.min(minDiff, root.val - prev.val); prev = root; inOrder(root.right); } } 1....
530. Minimum Absolute Difference in BST Given a binary search tree with non-negative values, find the minimum absolute difference between values of any two nodes. Example: Input:1 \ 3 / 2Output:1Explanation: Note: 思路1: 用一个list,存储全部的TreeNode。在list中,计算任意两个数之差的绝对值,...
