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
.

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.
