That would be somewhat different :)
'Who has the least results?' would mean that someone did not get as many results as other people did, not necessary the lowest
I was thinking more of 'Who has the lowest mark?' as it got marked wrong...
Have a nice day Jack
"wynik" is not a mark in school, unless there's some meaning that I'm not aware of?
"wynik" is like 12 in 4+8=12. And some other meanings.
"Least" does sometimes mean "smallest", so you could say "the least result" to mean "the smallest result". But in my experience, this usage is uncommon; it reminds me of a phrase from the King James Version, "the least of these my brethren".
As far as numbers go, "the least" and "the lowest" mean the same thing.
