WA100求助!

P1464 Function

@[Diamond_ZuanShi](/user/901793) ,把能开long long的都开开,或直接`#define int long long `就过了,求关

OK,已关。 PS:@[goIdie](/user/1041965) 能互关吗?

@[Diamond_ZuanShi](/user/901793) ,目前不太支持

不对,我代码好像发错了,我再发一遍,sorry ```cpp #include<bits/stdc++.h> using namespace std; long long x,y,z,ans[155][155][155]; long long 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(ans[a][b][c])return ans[a][b][c]; if(a<b&&b<c)ans[a][b][c]=w(a,b,c-1)+w(a,b-1,c-1)-w(a,b-1,c); else ans[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 ans[a][b][c]; } int main() { while(cin>>x>>y>>z) { if(x==-1&&y==-1&&z==-1)break; cout<<"w("<<x<<", "<<y<<", "<<z<<") = "<<w(x,y,z)<<endl; } return 0; } ```

@[goIdie](/user/1041965) long long main()?

@[ouxiyao](/user/1155764) ,可以改成`signed main`

对不起,我发现我帖子里的错误代码好像贴错了,真正的错误代码在第四个帖,辛苦各位大佬再帮我看看。

x,y,z为long long ,读进函数变成int了? 还有,题目说了,x,y,z有一个大于20就全部变为20,防止爆数据,特判在主程序
