Rolf,
If it is homework, I have to wonder at what level the class is before any of
the proposed answers would be considered acceptable by the instructor. For a
true beginner who has not even learned that much of R is vectorized, we are
back to perhaps using a manual loop with indices and ...
I will say that these days, I see too many assignments handed in by novices,
such as 12-year-old kids that strike me as clearly done with help even beyond
what a parent might have used in days gone by. I have done keyword searches and
found copying whole paragraphs and graphs and images from sources like Wiki,
propaganda included, and, of course, in programming courses, code. Sometimes it
is even simpler and assembled by an "AI" which implicitly did the equivalent of
a guided internet search.

Looks suspiciously like a homework question to me.
