Design a function f, so D f 3 will arrange the rows in order from small to large values in column 3 andD f 1 will do the same for column 1.
A=:(<30),(<'CAT'),<11 B=:(<18),(<'GOAT'),<10 C=:(<27),(<'BAT'),<9 [D=:A,B,:C ---T----T--┐ │30│CAT │11│ +--+----+--+ │18│GOAT│10│ +--+----+--+ │27│BAT │9 │ L--+----+--- If you prefer 3 f D and 1 f D, that's OK.
