You are given an integer array sorted in ascending order (may contain duplicates), you need to split them into several subsequences, where each subsequences consist of at least 3 consecutive integers. Return whether you can make such a split. Example
package faceobject; import java.util.Arrays; public class Test { /** 加密问题 数据是小于8位的整数 先将数据倒序,然后将每位数字都加上5,再用除以10的余数代替该数据 然后将第一个和最后一个调换位置 */ public static void main(String[] args){ int x=123456; jiami1(x); System.out.println(); jiami2(x); } public stati
Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 讲一个排序好的数组转换成二叉搜索树,这题没想出来,基本上是参考别人的,边界条件应该注意一下: /** * Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *rig
