题目链接 给定一个字符串.输入是int& a*[]&, b, c*; 输出是 int&&[]* a;int& b;int&* c; 输入格式里逗号后面一定有个空格,把字母后面的符号逆序拿到前面来,按每个逗号分隔输出即可. 注意输出格式一定是定义类型+符号+空格+字母或字符串+分号. #include <iostream> #include <cstdio> #include <cmath> #include <cst…

题意:good element的定义是a[i]在1~i-1中任取三个数(可以重复)的和能等于a[i] 思路:vis[x]标记一下任两个数的和,处理a[i]时枚举1~i-1判断vis[a[i] - a[j]]是否被标记 #include <iostream> #include <cstdio> #include <fstream> #include <algorithm> #include <cmath> #include <deque>…

Gym - 101915A  Printing Books 题意:有一本书,从第X页开始,一共用了n位数字,求此书一共多少页.99就是两位数字,100就是三位数字. 思路:直接模拟即可,我用了一个high和一个low,因为我把数字按位数分成了几个部分,1-9,10-99,100-999等(实际上high会等于1000),这样就会low = 100,high = 999之类的了,如果遇到边界,比如刚开始时,low和high有所调整,比如low=x,high=999,以方便计算. #include<…
