Yaroslav and Algorithm

题意翻译

有一种程序，以一个字符串 $a$ 为输入，包括一些操作。 1. 每一次操作有两种，形如 $s_i>>w_i$ 或 $s_i<>w_i$，其中 $s_i,w_i$ 是长度不超过 $7$ 的只包含数字和 `?` 的字符串。 2. 运行这个程序会多次按顺序遍历所有的操作。每次遍历会找到第一个操作 $i$ 满足 $s_i$ 是 $a$ 的子串并将 $a$ 中的第一个 $s_i$ 替换成 $w_i$。如果找不到这样的操作，则程序停止。否则如果操作 $i$ 是形如 $s_i>>w_i$ 的，那么开始新一轮遍历，否则程序停止。 3. 程序的输出就是程序停止时的 $a$。 现在给出 $n$ 个数 $a_1,a_2,\ldots,a_n$，请你构造一个程序，要求对于每一个输入的 $a_i$，输出 $a_i+1$。

题目描述

Yaroslav likes algorithms. We'll describe one of his favorite algorithms. 1. The algorithm receives a string as the input. We denote this input string as $ a $ . 2. The algorithm consists of some number of command. Сommand number $ i $ looks either as $ s_{i} $ >> $ w_{i} $ , or as $ s_{i} $ <> $ w_{i} $ , where $ s_{i} $ and $ w_{i} $ are some possibly empty strings of length at most $ 7 $ , consisting of digits and characters "?". 3. At each iteration, the algorithm looks for a command with the minimum index $ i $ , such that $ s_{i} $ occurs in $ a $ as a substring. If this command is not found the algorithm terminates. 4. Let's denote the number of the found command as $ k $ . In string $ a $ the first occurrence of the string $ s_{k} $ is replaced by string $ w_{k} $ . If the found command at that had form $ s_{k} $ >> $ w_{k} $ , then the algorithm continues its execution and proceeds to the next iteration. Otherwise, the algorithm terminates. 5. The value of string $ a $ after algorithm termination is considered to be the output of the algorithm. Yaroslav has a set of $ n $ positive integers, he needs to come up with his favorite algorithm that will increase each of the given numbers by one. More formally, if we consider each number as a string representing the decimal representation of the number, then being run on each of these strings separately, the algorithm should receive the output string that is a recording of the corresponding number increased by one. Help Yaroslav.

输入输出格式

输入格式

The first line contains integer $ n $ $ (1<=n<=100) $ — the number of elements in the set. The next $ n $ lines contains one positive integer each. All the given numbers are less than $ 10^{25} $ .

输出格式

Print the algorithm which can individually increase each number of the set. In the $ i $ -th line print the command number $ i $ without spaces. Your algorithm will be launched for each of these numbers. The answer will be considered correct if: - Each line will a correct algorithm command (see the description in the problem statement). - The number of commands should not exceed $ 50 $ . - The algorithm will increase each of the given numbers by one. - To get a respond, the algorithm will perform no more than $ 200 $ iterations for each number.
