我想用递归来解,感觉思路很有意思,可惜不知道哪里出错了哦~~请大侠们帮帮忙(附代码)#include<iostream.h>
#include<string.h>
#include <stdio.h>
#include<math.h>
int i,t,temp,a;
int test(int k)
{
if(k==0) return 0;
else
{
a=test(k-1);
t=a-k;
if(t>0)
{
temp=1;
for(i=0;i<k;i++)
{
if(test(i)==t)
{
temp=0;
break;
}
}
if(temp==1) return t;
}
else
return test(k-1)+k;
}
}
int main()
{
int num,k;
while(cin>>k)
{
if(k==-1) return 1;
num=test(k);
cout<<num<<endl;
}
return 1;
}
