Chain Cleanup Steps
Chain Cleanup Steps
Chaining works best when each step has one job. A cleanup pipeline might trim values, remove blanks, and then transform the remaining values into the display format the UI expects.
The order matters because blank strings are easier to detect after trimming. Once the unwanted values are gone, the remaining tags can be transformed without special cases.
Your task: Complete cleanTags so it returns lowercase, trimmed tags and removes blank entries. Preserve the order of the nonblank tags.
