Your tons of code make me laugh. +1 Clever for making my day, big brain :)

Function .rfind reads the "str" string and returns position of "ending" string from 0 to (.size - 1) or returns -1 if nothing is found. It's very useful to check where should be "ending" and form right condition.

Ty. I know that there are other methods, but I want complete this code by this method. I used size and length too, but it was completely usefull.

As I know, length is for string, but is a vector, that means dinamic array of strings. I used names.size()
