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....
We need to find the absolute difference of all elements of the tuple and count the frequency occurrence of the absolute difference and sort the list accordingly. A way to sort the list of tuples using absolute difference is by first computing the absolute difference of each tuple using theabs...

Mean absolute error (MAS) is an average of the absolute difference between the predicted and the true values, as follows: The MAS is less sensitive to the outliers, but it is also sensitive to the mean and scale.目录 上一章 下一章首页...
