left shift on lists

Stream: general

[Chris Hughes]

Is there a function on lists that rotates the elements of the list i.e [1, 2, 3, 4] -> [2, 3, 4, 1]?

[Simon Hudon]

For list xs, you can do it with drop 1 xs ++ take 1 xs

[Kevin Buzzard]

you'd better remember what you dropped :-)

[Simon Hudon]

yep! That's whattake 1 xs does
