第一行输入一个整数q，代表操作总数
以下q行每行描述了一个操作，每行以一个整数t开始（1 <= t <= 4）。
t表示上述问题陈述中定义的操作类型。 如果操作需要参数，则后跟空格分隔的参数。
题目保证所有操作均合法
1 <= q <= 10^6
1 <= k <= |记事本内容长度|
每个测试数据中str的总长度 <= 10^6
请使用 ios::sync_with_stdio(false); 对读写进行加速
所有操作类型3必须输出第k个字符，每行以换行符结束。
8 1 ab 3 2 2 2 1 cd 3 1 4 4 3 1
b c a
**样例解释**
假设记事本用字符串S表示
1、插入ab，S="ab"
2、输出第2个字符，是b
3、删除最后2个字符，S=""
4、插入cd, S="cd"
5、输出第1个字符，是c
6、撤销，此时S=""
7、撤销，此时S="ab"
8、输出第1个字符，是a

从标准输入读入数据。
输入包含多组数据，第一行一个整数 T 代表数据组数。接下来依次描述每组数据，对于每组数据：
第一行输入正整数 N，第二行输入 N 个非负整数
1≤|A|≤30 （数组 A 的长度范围在 1 到 30 之间 ）
0≤A[i]≤10000 （数组 A 中的元素）
输出到标准输出。
对于每组数据，输出一行：
如果能划分成满足题目要求的数组 B 和 C 则输出 yes，否则输出no
