```cpp
#include<iostream>
#include<string>
#include<cstring>
using namespace std;
struct student{
int direct;//0朝向圈内 1朝向圈外
string name;
}a[100005];//数组1e5
int main() {
int n, m;
cin >> n >> m;
for (int i = 1; i <= n; i++) {
cin >> a[i].direct >> a[i].name;
}
int lr, s;//0为左 1为右
int pos = 1;
for (int i = 1; i <= m; i++) {
cin >> lr >> s;
if (a[pos].direct == 0 && lr == 0)pos = (pos - s + n) % n;
else if (a[pos].direct == 0 && lr == 1)pos = (pos + s) % n;
else if(a[pos].direct == 1 && lr == 0)pos = (pos + s) % n;
else if(a[pos].direct == 1 && lr == 1)pos = (pos - s + n) % n;
if(pos == 0)pos = n;// 0 表示是第 n 个小人
}
cout << a[pos].name;
}
