我......我补药......再......再TLE了!!!!

#include<bits/stdc++.h>
using  namespace  std;

    }
    if(a>20||b>20||c>20)

    }
    if(a<b&&b<c)
    {
        return w(a,b,c-1)+w(a-1,b-1,c)+w(a-1,b,c-1)-w(a-1,b-1,c-1);
    }
    return (a-1,b,c)+w(a-1,b-1,c)+w(a-1,b,c-1)-w(a-1,b-1,c-1);

  while(cin>>a>>b>>c)
  {
      if(a==-1&&b==-1&&c==-1)
      {
          break;    
      }
      cout<<"w("<<a<<", "<<b<<", "<<c<<") = "<<w(a,b,c)<<endl;
  } 
  return  0;
}

样例可过求调QAQ
