Find the least number $$$M$$$ that includes $$$X$$$ as the leading digits and also $$$M$$$ is a multiple of $$$Y$$$.
Input
The input consist of 2 integers of form $$$X$$$ $$$Y$$$
$$$1\le X \le 10^{18}$$$
$$$1\le Y \le 10^{9}$$$
Output
Output the value of $$$M$$$
Examples
Input
33 11
Output
33
Input
50 3
Output
501
Note
In second test case values of $$$M$$$ are $$$50,500,501,502...$$$ and so on.
Since $$$501$$$ is the smallest value of $$$M$$$ which is divisible by $$$Y=3$$$,, Hence $$$501$$$ is our answer.
