把那个问题改过来真的还是错的QAQ
```cpp
#include<cstdio>
#include<iostream>
#include<algorithm>
using namespace std;
typedef long long ll;
inline void read(int &x) {
char ch=getchar(); int f=1;x=0;
for( ; !isdigit(ch); ch=getchar()) if(ch=='-') f=-1;
for(;isdigit(ch); x=x*10+ch-'0',ch=getchar()); x*=f;
}
inline void read(ll &x) {
char ch=getchar(); ll f=1;x=0;
for( ; !isdigit(ch); ch=getchar()) if(ch=='-') f=-1;
for(;isdigit(ch); x=x*10+ch-'0',ch=getchar()); x*=f;
}
inline void write(int x){
int top=0;char tmp[10]="";
do{tmp[++top]='0'+x%10;x/=10;}while (x);
while ( top ) putchar( tmp [ top -- ] );
}
inline void write(ll x){
int top=0;char tmp[30]="";
do{tmp[++top]='0'+x%10;x/=10;}while (x);
while ( top ) putchar( tmp [ top -- ] );
}
inline void write(int x,char c){
int top=0;char tmp[10]="";
do { tmp[++top]='0'+x%10; x/=10; } while (x);
while(top)putchar(tmp[top--]);putchar(c);
}
inline void write(ll x,char c){
int top=0;char tmp[30]="";
do { tmp[++top]='0'+x%10; x/=10; } while (x);
while(top)putchar(tmp[top--]);putchar(c);
}
inline int fianl(int &x){int t=0;while (x>t)x-=t++;return t;}
struct ans{int a;char c='/';int b=1;};
inline ans solve(int t,int x){
ans m;m.a=t;
for (int i=1;i<x;++i)m.a--,m.b++;
if (!(t&1))swap(m.a,m.b);
return m;
}
int main(){
int x;read(x);
int t=fianl(x);
printf("%d%c%d\n",solve(t,x));
return 0;
}
```

@[K_Vin](/space/show?uid=21836) 废话，当然不能输出结构体，想输出结构体要重载的
```cpp
ostream& operator << (ostream& out,const ans &x)
{
out<<x.a<<'\'<<x.b;
return out;
}
```

@[DimensionTripper](/space/show?uid=55454) 能输出结构体，用printf输出，顺序是结构体定义时变量的顺序，你可以试试。

@[K_Vin](/space/show?uid=21836) 欸，这么厉害吗？！

@[DimensionTripper](/space/show?uid=55454) 可能是因为我编译用了std=c++11？？
