I’ve a list of strings Dad, mam, Junior, Richard. Let’s say, I remove Junior whose index is 2 from the list. Is richard’s index becomes 2 or is still 3 with a gap at the second position?
Thanks for helping

No gap. If you want a gap replace the value at that position with
nullyourself.Mostly you don’t want a gap, so you can be happy that it’s kept tidy for you.
One practical consequence though, is that if you are going to be removing a lot of items in the same operation, you may find it faster to build a new list with only those you aren’t removing (because it moves things around internally after each remove).
It has to be a lot for that to be worth while though. Bear it in mind if you hit a big delay, rather than jumping straight into taking that approach first thing.
