2016-6: Shorter Ones to the Front
Write a function that takes a vector of vectors as its right argument and returns it sorted by the length of each element. An element of the vector can be scalar or an empty vector.
Examples:
(your_function) 'one' 'two' 'three' 'four' 'five' 'six'
┌───┬───┬───┬────┬────┬─────┐
│one│two│six│four│five│three│
└───┴───┴───┴────┴────┴─────┘
(your_function) (2 4 3) (4 5) 1 (7 3)
┌─┬───┬───┬─────┐
│1│4 5│7 3│2 4 3│
└─┴───┴───┴─────┘
(your_function) ⍬ ⍝ should return an empty vector
(your_function) 'one' 2 'three' '' 'four' (5 6 7 8)
┌┬─┬───┬────┬───────┬─────┐
││2│one│four│5 6 7 8│three│
└┴─┴───┴────┴───────┴─────┘
