。。。
以后仔细点
```cpp
#include <iostream>
#include <string>
#include <algorithm>
#define maxn 100005
int lr[maxn], c[maxn], d[maxn], num = 1, sum = -1;
char name[maxn][15];//char name[maxn][maxn];这里后面一个大小开错了，这就解释了你为什么数组开大反而RE得多，空间爆了
using namespace std;
int main() {
int n, m, a, s;
cin >> n >> m;
for (int i = 1; i <= n; i++) {
cin >> lr[i] >> name[i];
}
for (int i = 1; i <= m; i++) {
cin >> a >> s;
if (lr[num] == 0) {
if (a == 0) {
num -= s;
} else num += s;
} else {
if (a == 0) {
num += s;
} else num -= s;
}
while (num > n) num -= n;
while (num <= 0) num += n;//这里可以不改，写while安全一点，不改也没关系
}
cout << name[num]<<endl;
}
```

AC了，不仅是二维开大了，而且maxn开小了。。。
