##### Canadian Computing Competition: 2017 Stage 1, Junior #2

Suppose we have a number like . Let's define *shifting a number* to mean adding a zero at the end. For example, if we shift that number once, we get the number . If we shift the number again we get the number . We can shift the number as many times as we want.

In this problem you will be calculating a *shifty sum*, which is the sum of a number and the numbers we get by shifting. Specifically, you will be given the starting number and a non-negative integer . You must add together and all the numbers you get by shifting a total of times.

For example, the shifty sum when is and is is: . As another example, the shifty sum when is and is is .

#### Input Specification

The first line of input contains the number . The second line of input contains , the number of times to shift .

#### Output Specification

Yes, because you submitted an editorial solution to a lot of problems without solving them yourself before. Each editorial is accompanied by a large warning that copy/pasting editorials can lead to bans on submitting a problem, so is it a surprise that you got banned doing so?

I've unbanned you from this problem, but this isn't something that'll happen again.
