题目描述: 不用+,-求两个数的和 原文描述: Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -. Example: Given a = 1 and b = 2, return 3. 方法一:用位运算模拟加法 思路1: 异或又被称其为"模2加法" 设置变量recipe模拟进位数字,模拟加法的实现过程 代码: public class Solutio…
Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 m…

Two Sum 两数之和 Given an array of integers, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Plea…
Part 1. 题目描述 (easy) Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. Example: Given n…
Design and implement a TwoSum class. It should support the following operations: add and find. add - Add the number to an internal data structure.find - Find if there exists any pair of numbers which sum is equal to the value. For example, add(1); ad…
Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -. Example:Given a = 1 and b = 2, return 3. 题目标签:Bit Manipulation 这道题目让我们做两数之和,当然包括负数,而且不能用+,-等符号.所以明显是让我们从计算机的原理出发,运用OR,AND,XOR等运算法则.一开始自己想的如果两个数都是正数,那么很简单,…

Given a Binary Search Tree and a target number, return true if there exist two elements in the BST such that their sum is equal to the given target. Example 1: Input: 5 / \ 3 6 / \ \ 2 4 7 Target = 9 Output: True Example 2: Input: 5 / \ 3 6 / \ \ 2 4…
问题1 用来测试的,就不说了 问题2:中位数附近2k+1个数 给出一串整型数 a1,a2,...,an 以及一个较小的常数 k,找出这串数的中位数 m 和最接近 m 的小于等于 m 的 k 个数,以及最接近 m 的大于等于 m 的 k 个数.将这 2k+1 个数按升序排序后输出. 中位数定义:如果数串的大小是偶数 2j,中位数是从小到大排列的第 j 个数:如果数串的大小是奇数 2j+1,中位数是从小到大排列的第 j+1 个数. 输入 第一行是 k 的值和数串的长度 n. 第二行是以空格隔开的 n…
