Given a list of elements, create and return a list whose elements are lists that contain the consecutive runs of equal elements of the original list. Note that elements that aren’t duplicated in the original list should become singleton lists in the result, so that every element gets included in the resulting list of lists.

Input: List of str and int.

Output: List of lists of str and int

Example:

group_equal([1, 1, 4, 4, 4, "hello", "hello", 4]) == [[1,1],[4,4,4],["hello","hello"],[4]]
group_equal([1, 2, 3, 4]) == [[1], [2], [3], [4]]
group_equal([1]) == [[1]]
group_equal([]) == []
