Problem DescriptionThese days, I am thinking about a question, how can I get a problem as easy as A+B? It is fairly difficulty to do such a thing. Of course, I got it after many waking nights.Give you some integers, your task is to sort these number ascending (升序).You should know how easy the proble 阅读全文

还记得中学时候学过的杨辉三角吗？具体的定义这里不再描述，你可以参考以下的图形：11 11 2 11 3 3 11 4 6 4 11 5 10 10 5 1Input输入数据包含多个测试实例，每个测试实例的输入只包含一个正整数n（1<=n<=30），表示将要输出的杨辉三角的层数。Output对应于每一个输入，请输出相应层数的杨辉三角，每一层的整数之间用一个空格隔开，每一个杨辉三角后面加一个空行。Sample Input2 3Sample Output1 1 1 1 1 1 1 2 1#include<stdio.h>int main(){int n, num[32][32 阅读全文

Problem Description参加过上个月月赛的同学一定还记得其中的一个最简单的题目，就是{A}+{B}，那个题目求的是两个集合的并集，今天我们这个A-B求的是两个集合的差，就是做集合的减法运算。（当然，大家都知道集合的定义，就是同一个集合中不会有两个相同的元素，这里还是提醒大家一下）呵呵，很简单吧？Input每组输入数据占1行,每行数据的开始是2个整数n(0<n<=100)和m(0<m<=100),分别表示集合A和集合B的元素个数，然后紧跟着n+m个元素，前面n个元素属于集合A，其余的属于集合B. 每个元素为不超出int范围的整数,元素之间有一个空格隔开.如果 阅读全文
