#include <bits/stdc++.h>
using namespace std;
int read(){
int ret=0,f=1;char ch=getchar();
while(!isdigit(ch)){if(ch=='-')f=-f;ch=getchar();}
while( isdigit(ch)){ret=(ret<<3)+(ret<<1)+(ch&15);ch=getchar();}
return ret*f;
}
int T;
int n;
int main(){
T=read();
while(T--){
n=read();
int L=1,R=n;
while(L<R){
int p=(L+R+1)>>1;
double now=1.0*(p-1)/2+1.0*n/p;
if(p<=now+1) L=p;
else R=p-1;
}
long long a=1ll*L*(L-1)/2+n,b=L;
printf("%lld %lld\n",a/__gcd(a,b),b/__gcd(a,b));
}
return 0;
}
这程序好像有点Bug，我给组数据试试？
