Challenge #24 - Remove Extras

Create a function that takes two arguments: a list and a number. In the list (the first argument), if an element occurs more than N times (the second argument), remove the extra occurrences and return the result.

Examples

delete_occurrences([1, 1, 1, 1], 2) ➞ [1, 1]

delete_occurrences([13, True, 13, None], 1) ➞ [13, True, None]

delete_occurrences([True, True, True], 3) ➞ [True, True, True]

Notes

• Do not alter the order of the original list.
