Count How Many Times an Element is Repeated

Given a list, create a function that returns a dictionary detailing how many times each element was repeated.

Examples

count_repetitions(["cat", "dog", "cat", "cow", "cow", "cow"]) ➞ { cow: 3, cat: 2, dog: 1 }

count_repetitions([1, 5, 5, 5, 12, 12, 0, 0, 0, 0, 0, 0]) ➞ { 0: 6, 5: 3, 12: 2, 1: 1 }

count_repetitions(["Infinity", "null", "Infinity", "null", "null"]) ➞ { "null": 3, "Infinity": 2}
