但是改完似乎尚未AC，今天突然发现没开long long

#include<bits/stdc++.h>
#define int long long
using namespace std;
int a , b , c;
int f[33][33][33];
int w (int a , int b , int c)
{
    if (a <= 0 || b <= 0 || c <= 0)return 1;
    else if (f[a][b][c] > 0)return f[a][b][c];
    else if (a > 20 || b > 20 || c > 20)return f[20][20][20];
    else 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];
}
signed main()
{
    int sum = 1;
    for (int i = 1; i <= 20; ++ i){sum *= 2;f[i][i][i] = sum;}
    while (scanf ("%lld %lld %lld" , &a , &b , &c))
    {
        if (a == -1 && b == -1 && c == -1)break;
        printf ("w(%lld, %lld, %lld) = " , a , b , c);
        a = a > 20 ? 21 : a;
        b = b > 20 ? 21 : b;
        c = c > 20 ? 21 : c;
        printf ("%lld\n" , w (a , b , c));
    }
    return 0;
}

呵呵
