模拟

没怎么看题。。直接deque模拟水过了。。
但是后来回过头看了下题意。。如果再次拿到正面朝上的牌，应该是废操作。。可能是数据太水了。。。

#include <bits/stdc++.h>
#define INF 0x3f3f3f3f
#define full(a, b) memset(a, b, sizeof a)
using namespace std;
typedef long long ll;
inline int lowbit(int x){ return x & (-x); }
inline int read(){
    int X = 0, w = 0; char ch = 0;
    while(!isdigit(ch)) { w |= ch == '-'; ch = getchar(); }
    while(isdigit(ch)) X = (X << 3) + (X << 1) + (ch ^ 48), ch = getchar();
    return w ? -X : X;
}
inline int gcd(int a, int b){ return a % b ? gcd(b, a % b) : b; }
inline int lcm(int a, int b){ return a / gcd(a, b) * b; }
template<typename T>
inline T max(T x, T y, T z){ return max(max(x, y), z); }
template<typename T>
inline T min(T x, T y, T z){ return min(min(x, y), z); }
template<typename A, typename B, typename C>
inline A fpow(A x, B p, C lyd){
    A ans = 1;
    for(; p; p >>= 1, x = 1LL * x * x % lyd)if(p & 1)ans = 1LL * x * ans % lyd;
    return ans;
}

        }
    }

    q[12].pop_front();
    while(tmp < 4){
        if(cur == 12){
            tmp ++, cur = m[q[12].front()], q[12].pop_front();
            continue;
        }
        vis[cur] ++;
        if(vis[cur] == 4) ans ++;
        int temp = cur;
        cur = m[q[temp].back()], q[temp].pop_back(), q[temp].push_front(s[temp]);
    }
    printf("%d\n", ans);
    return 0;
