New Algorithm

CodeChefOpen on judge ↗

Little Praneet loves experimenting with algorithms and has devised a new algorithm. The algorithm is performed on an integer as follows: - if the rearmost digit is $0$, he will erase it. - else, he will replace the rearmost digit $d$ with $d-1$. If a point comes when the integer becomes $0$, the algorithm stops. You are given an integer $n$. Praneet will perform the algorithm on it $a$ t
