How do you get the second to last digit of a number?

Steps

1. Let N be the input number.
2. If N is a one-digit number, return -1.
3. Set N = N / 10. This step removes the last digit of N.
4. N \% 10 gives us the last digit of N. Since we have already removed the last digit of N in the previous step, N \% 10 is equal to the second last digit of the input number.
5. Return N \% 10.
