这个程序为什么WA 求给组数据指明问题!#include<cstdio> #include<iostream> #include<algorithm> #include<cmath> long long gcd(int a,int b){ if(a%b==0)return b; else return gcd(b,a%b); } int main(){ long long g,l,j; scanf("%I64d%I64d",&g,&l); for(long long i=0;i<sqrt(g*l);i++){ long long a=sqrt(g*l)-i; long long b=g*l/a; if(a*b!=l*g)continue; if(gcd(b,a)==g){ printf("%I64d %I64d\n",a,b); break; } } return 0; } Followed by: Post your reply here: |
