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

int main()
{
    int F, N;
    int ab=0;
    int a[N];

直接將猜拳順序輸入儲存

    cin >> F >> N;
    for (int i=0; i<N; i++){
        cin >> a[i];    // 妹妹預先出的拳
    }
    
使用迴圈檢查

    for (int i=0; i<N; i++){
        
        if (a[i-2]==a[i-1]){

簡單條件判斷

            
            if (a[i-1]==0)  // 如果妹妹前兩次出石頭
               { F = 5; cout << F<< " ";}
            else if (a[i-1]==2)  // 如果妹妹前兩次出剪刀
               { F = 0; cout << F<< " ";}
            else if (a[i-1]==5)  // 如果妹妹前兩次出布
               { F = 2; cout << F<< " ";}
            }else{cout << F<< " ";}
        
        if((a[i]==0 && F==2) || (a[i]==2 && F==5) || (a[i]==5 && F==0)){ 
            cout << ": Lost at round " << i+1; ab = 1; break;
          } else if ((a[i]==2 && F==0) || (a[i]==5 && F==2) || (a[i]==0 && F==5)){
              cout << ": Won at round " << i+1; ab = 1; break;
          }
    }
    
    if (ab==0)
    {cout << ": Drew at round "<< N;}

    return 0;
}
