Score : $200$ points

Problem Statement

You are given an integer $N$.
Do the following operation $K$ times on it and print the resulting integer.

• If $N$ is a multiple of $200$, divide it by $200$.
• Otherwise, see $N$ as a string and append $200$ to the end of it.
  • For example, $7$ would become $7200$ and $1234$ would become $1234200$.

Constraints

• All values in input are integers.
• $1 \le N \le 10^5$
• $1 \le K \le 20$

Input

Input is given from Standard Input in the following format:

$N$ $K$

Output

Print the answer as an integer.
