help!!!

全TLE能理解，麻烦大家找下那唯一一个re错哪了，新学递归（没学太好可能递归就错了），不求AC，过来练习一下，谢谢

# include<bits/stdc++.h>
using namespace std;
int 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(a < b && b < c) return w(a, b, c - 1) + w(a, b - 1, c - 1) - w(a, b - 1, c);
    else return w(a - 1, b, c) + w(a - 1, b - 1, c) - w(a - 1, b - 1, c - 1);
}

        << w(a[i], b[i], c[i]) << endl;
