you god damn right

sum() accepts any iterable so it's not necessary (and actually slower) to materialise the list before passing it to sum. You can leave out the square brackets in which case this will work like a generator expression and pass individual values to sum as sum requests them.

Big brain alert!!

It has less complexity (only sorts n items instead of len(xs)), so for large xs's and small n's its worst case should be better. Performance on real-world data is to be tested.

how does it work? ))

nice

Fastest solution! great
