I am Sherlocked

Detectives of Scotland Yard, the headquarters of the Metropolitan Police, informed Sherlock Holmes about a cyber attack on the Central Bank by James Moriarty. They also found a secret code that can stop the attack. According to their top agent, Moriarty hid the code in the phonebook of one of his clients. Sherlock has access to this client.

Each correct phone number has 11 digits and starts with a leading zero. The client may separate the digits of each phone number with hyphens (-) or spaces. Some phone numbers in the phonebook may be missing the leading zero. For example, 09163264128 might be written as 916 32 64 128, or even as - 0916-16-32--64 - 128-.

Sherlock arranged a friendly conversation with the client at a cafe. Meanwhile, Dr. John Watson, Sherlock's colleague, took the phonebook without the client noticing. Sherlock told Dr. Watson to clean the phonebook into a new sequence $C$ of digit characters on his computer. $C$ is zero-indexed. Dr. Watson types the phone numbers one after another, in the order they appear, with all non-digit characters removed. He adds the leading zero where it is needed.

Dr. Watson has prepared $C$ and placed the cursor at the first character. The cursor can be placed before any character of $C$. He waits for Sherlock's instructions to produce the output sequence $S$. Sherlock sends one of the following instructions.

• go $i$: Moves the cursor to the beginning of the $i$th cleaned phone number in $C$. For example, go 0 moves the cursor to the first phone number.
• forward $i$: Moves the cursor forward by $i$ digits.
• backward $i$: Moves the cursor backward by $i$ digits.
• next $i$: Writes the next $i$ digits starting at the cursor into $S$. If the cursor is before position $c$, the digits at $c, c + 1, \dots, c + i - 1$ are written. The cursor does not move.
• pick $i$ $j$: If $i < j$, writes the digits at positions $i, i + 1, \dots, j$ of the current phone number into $S$. Otherwise, writes the digits at positions $i, i - 1, \dots, j$. The current phone number is the one that the digit after the cursor belongs to. The cursor does not move. Note that $0 \le i, j \le 10$, and pick 0 0 writes the first digit.

Sherlock may also send the following instruction to correct a mistake.

• delete $i$: Deletes the last $i$ digits from the end of $S$.

The input consists of the phonebook's content and Sherlock's instructions. The phonebook contains $n$ phone numbers ($1 \le n \le 1{,}000$), separated by commas or newlines. Each phone number is a string of 10 or 11 digits (0-9), possibly with hyphens and/or spaces. The phonebook has at most $10^6$ characters. The list of phone numbers ends with a line containing only the character #.

Each remaining line contains one of Sherlock's instructions. He sends at most 10,000 instructions. All arguments are non-negative integers no greater than 20,000. Every instruction is one of the six listed above.

Print the extracted secret code, which is a string of digits. The code may be empty. If the code has more than 10,000 digits, print only the first 10,000 digits.

Sherlock may lose focus and send a malformed instruction. This happens when go refers to a phone number that does not exist, or when forward, backward, next, pick, or delete has an argument that refers to a digit or phone number that does not exist in $C$. In such cases, Moriarty has succeeded, and you must print MISS ME! in capital letters.
