Did you ever learning math?

Hello - I was experimenting with using a subset of string handling, to see if I could get the algorithm working. But you are correct - there are much better (quicker) ways of getting the same effect with built-in functions! Thanks, and stay safe! :-)

ohh shit bro i worte 8 lines of code to this program,but you finished this program in one line ,nice man......

yeah, we could have write list as string and avoid int parse thing but nvm

2, 69, 301, 280013 - good
(5), (5)6, 2(5)0, 12321(5) - bad
