On the TI-83/+, this sorts L1 and L2 in parallel, as if you were sorting
pairs of elements indexed on the first element. That is, L2 ends up as
{1,4,2,3}.

Because if LHIGH was {1,2,3,4,5} and you took max(LHIGH), you would *not*
get the highest value of LHIGH(1), LHIGH(2), LHIGH(3), LHIGH(4); instead,
you'd get the maximum of the entire list, which would be 5. The OP asked
about four-element maxima in particular.
