没看懂qwq

有测试点过吗？

我代码这么写的,可以看看：
```c++
#include<bits/stdc++.h>
using namespace std;
long long a,b,c,f[30][30][30];
long long w(long long a,long long b,long long c)
{
if(a<=0||b<=0||c<=0)
{
return 1;
}
if(a>20||b>20||c>20)
{
return w(20,20,20);
}
if(f[a][b][c])
{
return f[a][b][c];
}
if(a<b&&b<c)
{
return f[a][b][c]=w(a,b,c-1)+w(a,b-1,c-1)-w(a,b-1,c);
}
else
{
return f[a][b][c]=w(a-1,b,c)+w(a-1,b-1,c)+w(a-1,b,c-1)-w(a-1,b-1,c-1);
}
}
int main()
{
while(scanf("%lld%lld%lld",&a,&b,&c)==3)
{
if(a==-1&&b==-1&&c==-1)
{
break;
}
printf("w(%lld, %lld, %lld) = %lld\n",a,b,c,w(a,b,c));
}
return 0;
}

在让我看下你现在的代码
