给定一个正整数，输出其补码。补码策略是翻转其二进制表示的位。 注意：   给定的整数保证在32位有符号整数的范围内。 您可以假定整数二进制表示中没有前导零位。 示例1：   输入： 5  输出：2  说明：5的二进制表示为101（无前导零位），其补码为010，所以需要输出2。 示例2： 输入： 1   输出： 0  说明：1的二进制表示为1（无前导零

Writea function to delete a node (except the tail) in a singly linked list, givenonly access to that node. Supposed the linked list is 1 -> 2 -> 3 -> 4 and you are given thethird node with value

Given an array of 2n integers, your task is to groupthese integers into n pairsof integer, say (a1, b1), (a2, b2),..., (an, bn) which makes sum of min(ai, bi) forall i from 1 to n as large as po

Reverse digits of aninteger. Example1: x = 123, return 321 Example2: x = -123, return -321   给你一个整数,返后它倒序的数字 最好就是用数学运算来解决这个问题,让这个数循环除以10取余,然后让输出的数字循环乘以10然后加上当前取余的结果,是一种类似位运算的思想,可以

The Hammingdistance between two integers is the number of positions atwhich the corresponding bits are different. Given two integers x and y, calculate the Hamming distance. Note:  0 ≤ x, y < 2

Write a program thatoutputs the string representation of numbers from 1 to n. But for multiples of threeit should output “Fizz” instead of the number and for the multiples of fiveoutput “Buzz”. For n

Write a program to find the node at which the intersection of two singly linked lists begins.   For example, the following two linked lists: A:      a1 → a2                 ↘                   ...
