# Palindromes In Base 11

Let $$n$$ be a $$m$$-digit palindromic number (where $$m\geq 2$$ is even) in base 10.

What is the units digit of $$n$$ when written out in base 11?

If you think the answer depends on the value of $$n$$ in base 10, enter -1 as your answer.

Details and Assumptions:

• The digits allowed in base 11 are digits 0-9 and A where $$\overline{A}_{11}=\overline{10}_{10}$$.

• If you think the answer depends on the value of $$n$$ in base 10, enter -1 as your answer.
