Question 69
Positive integer $n$ has no more than $2020$ digits. Prove that there exist $m$ such palindromes that their sum equals $n$, where $m \le 13$.
A palindrome is a number which is read the same both left to right and right to left, i.e. $1001$, $9$ and $767$ are palindromes, while $1212$ and $110$ are not.
