Problem Description Given an positive integer A (1 <= A <= 100), output the lowest bit of A. For example, given A = 26, we can write A in binary form as 11010, so the lowest bit of A is 10, so the output should be 2. Another example goes like this:…

Given a binary search tree (BST), find the lowest common ancestor (LCA) of two given nodes in the BST. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has…

水题,原理是计算机组成原理中的负数的补码的求码.利用按位与可解. #include <iostream> using namespace std; int main() { int n; ) { cin >> n; ) break; cout <<(n&(-n))<<endl; } ; }…

题目大意是给一个1-100的整数,要求首先转化成2进制,然后从最低位开始数起到不是0的位停止,输出这些位代表队额10进制数 #include <iostream> using namespace std; ]={,,,,,,}; int judge(int a)//判断输入数据的范围 { ) ; &&a>=) ; &&a>=) ; &&a>=) ; &&a>=) ; &&a>=) ;…

时间限制:1 秒 内存限制:32 兆 特殊判题:否 提交:4339 解决:1476 题目描述: 用一维数组存储学号和成绩,然后,按成绩排序输出. 输入: 输入第一行包括一个整数N(1<=N<=100),代表学生的个数. 接下来的N行每行包括两个整数p和q,分别代表每个学生的学号和成绩. 输出: 按照学生的成绩从小到大进行排序,并将排序后的学生信息打印出来. 如果学生的成绩相同,则按照学号的大小进行从小到大排序. 样例输入: 3 1 90 2 87 3 92 样例输出: 2 87 1 90 3…
