Problem Statement

Given an integer, n, between 0 and 9, generate the n+1 number.

You can use your preferred conditional to solve this problem.

Sample Input

n = 3

Sample Output

Coding Challenge

Take some time to figure out all the possible cases for the values of n. Keep in mind that n can go up to 9, which means the last number in the whole sequence will be 10.

For any value of n outside the specified range, just return -1.
