We would like to find the minimum number of steps required to get 0 from any number, when you can only subtract a digit present in that number in a single step. For example, if you are given 25. Then you can either subtract 2 or 5 from 25. Let's subtract 5 then we will get 20. Then we can subtract 2 and get 18 and so on. The minimum number of steps to get from 25 to 0 is shown below: 25→20→18→10→9→0. Now you need to write a DP program to find the minimum number of steps to solve the problem for any input. Input range will be from 0 to 999. [Python Implementation]
