Expected behavior

jump_search([], 5) should return -1 when given an empty list or sequence, as an empty collection cannot contain the target search item.

Actual behavior

Calling jump_search([], 5) raises an IndexError: list index out of range:

Traceback (most recent call last):
  File "searches/jump_search.py", line 43, in jump_search
    while arr[min(step, arr_size) - 1] < item:
IndexError: list index out of range
