求解释!!!。。。老是WA 无语了#include <iostream> #include <stdio.h> #include <math.h> using namespace std; __int64 gcd(__int64 a,__int64 b) { __int64 temp; if(a<b) { temp=b;b=a;a=temp; } if(a%b==0) return b; else return gcd(a-b,b); } int main() { __int64 a,b,x,y; while(scanf("%I64d",&a)!=EOF) { scanf("%I64d",&b); x=(__int64)sqrt(b/a); int i=0; while(y>0) { y=(b/a)/(x+i); if((x+i)*y==b/a && gcd(x+i,y)==1) { if(y*a<(x+i)*a) printf("%I64d %I64d\n",y*a,(x+i)*a); else printf("%I64d %I64d\n",(x+i)*a,y*a); break; } i++; } } return 0; } Followed by: Post your reply here: |
