dfs

Code

 2  a using  namespace std;
 3  int SUM = 0 ;
 4  void the DFS ( int value, int num_cnt) {
 5       IF (num_cnt == 13 ) { // 13 cards you can sec I? ! 
. 6           SUM ++;         // Qi, counting back 
. 7           return ;
 . 8       }
 . 9       IF (value == 14 ) { // points over, and back 
10           return ;
 . 11       }
 12 is       for( Int I = 0 ; I <= . 4 ; I ++ ) {
 13 is           DFS (value + . 1 , num_cnt + I); // begin the next point card 
14       }
 15  }
 16  int main () {
 . 17       DFS ( . 1 , 0 );
 18 is       COUT SUM << << endl;
