A. Maximum GCD 题意: t组输入,然后输入一个n,让你在区间[1,n]之间找出来两个不相等的数a,b.求出来gcd(a,b)(也就是a,b最大公约数).让你求出来最大的gcd(a,b)是多少. 题解: 最大gcd(a,b),那就是n/2向下取整的结果.因为如果gcd(a,b)越大,那么a/gcd(a,b)或者b/gcd(a,b)的值肯定越小,最小也就是2了,所以输出n/2就行 代码: 1 #include<stdio.h> 2 #include<algorithm>…

题目:传送门 题意:求n个数的最大公约数,暴力不会超时,难点在没有个数控制的输入. 题解:用特殊方法输入. #include <iostream> #include <cmath> #include <cstdio> #include <cstring> using namespace std; int gcd(int a,int b) { ) return a; return gcd(b,a%b); } int main() { int t; cin>…

这题没什么好说的,但是输入较特别,为此还WA了一次... 题目链接: https://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&page=show_problem&problem=2927 题意: 输入m个数,求两两一组的最大GCD. 分析: 对stringstream不太熟悉,直接模拟字符串的输入,但是wa了. 我觉得wa的原因是,如果一行末尾有空格的话,就不能正确输入了...还求指正... int…
