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;

}
