What do you think about a function that return where is the min/max value in a
sequence
i = min ({1,7,9,-11,33,0,4.6,-4}) -- 4 is assigned to i (minimum is fourth
position)
i = max ({1,7,9,-11,33,0,4.6,-4}) -- 5 is assigned to i
Even an Eu Style max!!!
s = max ( { 1, 2, {3, 4}, 0}) -- {{3,2}}is assigned. The max is the
second element of the third element!!!!
When there are many elements whit the max value, return a sequence as:
s = max {1, 2, 3, 4, {1, 2, 3, 4}} -- {4, {5,4}} is assigned.
These are only ideas...
