Problem
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 <= 10000
1 <= barcodes[i] <= 10000
