Create a function that takes an array of numbers or strings and returns an array with the items from the original array stored into subarrays. Items of the same value should be in the same subarray.

Examples

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

advanced_sort([5, 4, 5, 5, 4, 3]) ➞ [[5, 5, 5], [4, 4], [3]]

advanced_sort(["b", "a", "b", "a", "c"]) ➞ [["b", "b"], ["a", "a"], ["c"]]

Notes

The subarrays should be returned in the order of each element's first appearance in the given array.
