Two elements of a binary search tree (BST) are swapped by mistake. Recover the tree without changing its structure. Note:A solution using O(n) space is pretty straight forward. Could you devise a constant space solution? 使用O(n)空间的话可以直接中序遍历来找问题节点. 如果是
题目描述: Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no
package 有序数组; public class OrdArray { private long[]array; private int nElems; //初始化 public OrdArray(int max){ array = new long[max]; nElems = 0; } //返回数组中的大小 public int size(){ return nElems; } //查找的方法的实现 public int find(long searchKey){ int lowerBo
题目描述: Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You may assume no duplicates in the array. Here are few examples. [1,3,5,6], 5 → 2 [1,3,5
题目描述: Given a sorted array of integers, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order of O(log n). If the target is not found in the array, return [-1, -1]. For example, Given
题目:矩阵单词搜索 难度:Medium 题目内容: Given a 2D board and a word, find if the word exists in the grid. The word can be constructed from letters of sequentially adjacent cell, where "adjacent" cells are those horizontally or vertically neighboring. The same

public class VerifyErrorextends LinkageError Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem. 后来在网上查到底这个错误是什么意思呢?这个错误指的是类是没有错误但是版本不统一,这让我更困惑了,这是自己写的一个类怎么会
