LeetCodeArrayHash TableGreedySortingHeap (Priority Queue)CountingOpen on judge ↗

In a warehouse, there is a row of barcodes, where the ith barcode is barcodes[i]. Rearrange the barcodes so that no two adjacent barcodes are equal. You may return any answer, and it is guaranteed an answer exists. Example 1: Input: barcodes = [1,1,1,2,2,2] Output: [2,1,2,1,2,1] Example 2: Input: barcodes = [1,1,1,1,2,2,3,3] Output: [1,3,1,3,1,2,1,2] Constraints: - 1 <= barcodes.length
