现代数学的著名证明之一是Georg Cantor证明了有理数是可枚举的。他是用下面这一张表来证明这一命题的: 1/1 1/2 1/3 1/4 1/5 … 2/1 2/2 2/3 2/4 … 3/1 3/2 3/3 … 4/1 4/2 … 5/1 … … 我们以Z字形给上表的每一项编号。第一项是1/1,然后是1/2,2/1,3/1,2/2,…

整数N(1≤N≤10000000)
表中的第N项
7
1/4
int main(){
int n,i,j,s,x=0;
scanf("%d",&n);
for(i=0;x*(x+1)/2<n;i++)x++;
s=n-x*(x-1)/2;
if(x%2!=0)printf("%d/%d\n",x+1-s,s);
else printf("%d/%d\n",s,x+1-s);
return 0;
}
