Processing Algorithms & Logic

• Deduplication: Strips leading/trailing whitespace and filters unique elements using a high-performance hash set ($O(N)$ time complexity).
• Natural Sorting: Uses locale-aware Unicode comparison supporting alphanumeric strings (e.g., Item 2 comes before Item 10).
• Random Selection: Uses cryptographic pseudo-random number generation (CSPRNG) for unbiased drawings.

Practical Everyday Examples

• Customer Email Cleaning: Paste 500 email lines $\rightarrow$ instantly removes 45 duplicate entries.
• Alphabetical Indexing: Sort a list of names or keywords from A to Z with one click.
• Fair Giveaway Drawing: Paste contest entrants and select "Pick a Random Item" for an impartial winner.

Common Applications

• Cleaning raw database exports, CSV columns, and email subscriber lists.
• Alphabetizing bibliographies, vocabulary lists, and product inventories.
• Conducting impartial giveaways, team assignments, and raffle drawings.

Input Specifications

• Deduplication is case-sensitive by default to preserve exact casing (e.g. "Apple" and "apple" are distinct).
• Lines are delineated by standard newline characters (\n, \r\n).
