Problem Description

In real life, we sometimes encounter some special numbers. If we write them in a special form, they become easier to remember and use. For example, $10^9+7$ is very common. Compared with $1000000007$, it is easier for contestants to read without counting the $0$'s, and it avoids the precision loss of scientific notation.

Now you are given a number of the form $10^{k}+x$. Please convert it back to the usual written form.

Input Format

One line with two integers $k,x$.

Output Format

Output one integer on one line, which is $10^k+x$.

9 7

1000000007

Hint

[Sample Explanation].

$10^9+7=1000000007$.

[Constraints].

This problem uses bundled tests. In other words, you can only get the score for a subtask if you pass all test points in that subtask.

For all testdata, $0\le x<10^{18}$, $0\leq k\leq 500$.
