1054. Distant Barcodes

Leetcode Solutions

Count the frequency of each barcode using a hash map.
Create a list of barcode-frequency pairs and sort it in descending order of frequency.
Initialize a new array result of the same length as barcodes.
Use two pointers, even and odd, to fill the result array. Start with even at index 0 and odd at index 1.
Iterate over the sorted list of barcode-frequency pairs.
While the frequency of the current barcode is greater than 0:
- Place the barcode at the even index and increment even by 2.
- If even exceeds the length of the array, start placing barcodes at the odd index and increment odd by 2.
Return the result array.
