21 points 3598180 small white or violence, this is after the test after the classmate told me ....  21 minutes, that's it.

Xiao Ming was hijacked to X Vegas and was forced to play cards with 3 other people.
A deck of poker (minus the size of ace, a total of 52), evenly distributed to 4 people, each 13 Zhang.

int Main(void) {int ans= 0; for(int A0= 0; A0 <= 4; a0++) { for(int A1= 0; A1 <= 4; a1++) { for(int A2= 0; A2 <= 4; a2++) { for(int A3= 0; A3 <= 4; a3++) { for(int A4= 0; A4 <= 4; a4++) { for(int A5= 0; A5 <= 4; a5++) { for(int A6= 0; A6 <= 4; a6++) { for(int A7= 0; A7 <= 4; a7++) { for(int A8= 0; A8 <= 4; a8++) { for(int A9= 0; A9 <= 4; a9++) { for(int A10= 0; A10 <= 4; a10++) { for(int A11= 0; A11 <= 4; a11++) { for(int A12= 0; A12 <= 4; a12++) {if(a0+a1+a2+a3+a4+a5+a6+a7+a8+a9+a10+a11+a12== 13)                                                        {ans++;                                            }                                                    }                                                }                                }                                        }                                    }         }                            }                        }                    }                }            } }} printf ("%d\n", ans);return0;}
