洛谷P1563 玩具谜题 简单模拟

没意义，注意方向别判错。

Code：

#include<cstdio>
#include<cstring>
using namespace std;
const int maxn = 100000 + 3;
char A[maxn][100];
int face[maxn];
int main()
{
   // freopen("in.txt","r",stdin);
    int n,m;
    scanf("%d%d",&n,&m);
    for(int i = 0;i < n; ++i)
    {
        scanf("%d",&face[i]);
        scanf("%s",A[i]);
    }
    int cur = 0;
    while(m--)
    {
        int a,s;
        scanf("%d%d",&a,&s);
        int flag = (face[cur] + a) % 2;
        if(flag == 1) cur = (cur + s + n) % n;
        if(flag == 0) cur = (cur - s + n) % n;
    }
    for(int i = 0;i < strlen(A[cur]); ++i)printf("%c",A[cur][i]);
    return 0;
}
