Moves the specified amount of elements to the end of the list.

Use lst[offset:] and lst[:offset] to get the two slices of the list and combine them before returning.

def offset(lst, offset):
  return lst[offset:] + lst[:offset]

offset([1, 2, 3, 4, 5], 2) # [3, 4, 5, 1, 2]
offset([1, 2, 3, 4, 5], -2) # [4, 5, 1, 2, 3]
