真是服了 cout 和printf换换样就不对了 c++又不支持cout<<了吗?真是的#include<iostream>
#include<memory.h>
using namespace std;
__int64 num[11000];
int main()
{
int i,n,j;
int temp=0;
memset(num,0,sizeof(num));
for(i=1;i*(i-1)/2<11000;i++)
{
temp=(i-1)*i/2;
for(j=1;j<=i;j++)
{
num[temp+j]=i+num[temp+j-1];
}
}
for(temp=temp+i-1;temp<11000;temp++)
num[temp]=i+num[temp-1];
//for(i=1;i<30;i++)
// cout<<num[i]<<" ";
while(scanf("%d",&n)&&n)
{
// cout<<n<<" "<<num[n]<<endl;
printf("%d %d\n",n,num[n]);
}
return 0;
}
