我最近学了快读，也了解到scanf比cin之类的要快。 就我目前代码而言，scanf比快读还快。 于是我有俩请求：

1. 求大佬帮忙分析下是不是代码的问题
2. 这两种输入是不是分情况？数据越大快读越快？

	int x, y, k=0;
	scanf("%d %d", &n, &m);
	for (int i = 0; i < n; i++) {
		scanf("%d", &a[i].nums);
		scanf("%s", a[i].name);
	}
	while (m--) {
		scanf("%d %d", &x, &y);

			if (k < 0) k += n;
		}****
		else if (a[k].nums != x) {
			k += y;
			if (k >= n) k -= n;
		}
	}
	cout << a[k].name;
}
