副ac代码：
代码如下：：
```cpp
#include<stdio.h>
int f[21][21][21];
int aa[10000],bb[10000],cc[10000];
int w(int a,int b,int 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] != f[0][0][0]) return f[a][b][c];
if(a<b&&b<c) f[a][b][c] = w(a,b,c-1)+w(a,b-1,c-1)-w(a,b-1,c);
else 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);
return f[a][b][c];
}
int main(){
int a,b,c,i,ii;
i=0;
while(a!=-1||b!=-1||c!=-1){
scanf("%d %d %d",&a,&b,&c);
aa[i]=a;bb[i]=b;cc[i]=c;
i++;
}
for(ii=0;ii<i-2;ii++){printf("w(%d, %d, %d) = %d \n",aa[ii],bb[ii],cc[ii],w(aa[ii],bb[ii],cc[ii]));}
printf("w(%d, %d, %d) = %d",aa[ii],bb[ii],cc[ii],w(aa[ii],bb[ii],cc[ii]));
return 0;
}
```

表示我边输入边输出AC了
