Combined Consecutive Sequence

Write a function that returns True if two arrays, when combined, form a consecutive sequence. A consecutive sequence is a sequence without any gaps in the integers, e.g. 1, 2, 3, 4, 5 is a consecutive sequence, but 1, 2, 4, 5 is not.

Examples

consecutive_combo([7, 4, 5, 1], [2, 3, 6]) ➞ True

consecutive_combo([1, 4, 6, 5], [2, 7, 8, 9]) ➞ False

consecutive_combo([1, 4, 5, 6], [2, 3, 7, 8, 10]) ➞ False

consecutive_combo([44, 46], [45]) ➞ True

Notes

• The input lists will have unique values.
• The input lists can be in any order.
