Who Left the List?

You are given two lists. The elements in lst1 threw a party and started to mix around. However, one of the elements got lost! Your task is to return the element which was lost.

Examples

missing([1, 2, 3, 4, 5, 6, 7, 8], [1, 3, 4, 5, 6, 7, 8]) ➞ 2

missing([True, True, False, False, True], [False, True, False, True]) ➞ True

missing(["Jane", "is", "pretty", "ugly"], ["Jane", "is", "pretty"]) ➞ "ugly"

missing(["different", "types", "5", 5, [5], (5,)], ["5", "different", [5], "types", 5]) ➞ (5,)

Notes

• Assume that the first list always contains 1 or more elements.
• Elements are always lost.
• An element can also have duplicates.
