技术架构与执行机制
Hash Set Deduplication Complexity
The deduplication algorithm splits the input string by newline characters and inserts each line into a JavaScript Set data structure. Lookup and insertion operate in average O(1) time complexity, yielding overall O(N) linear time performance.
Unique_Lines = Array.from(new Set(Raw_Lines.map(l => l.trim())))技术限制与运行约束
- Very large lists exceeding 500,000 lines may experience slight interface pause during DOM rendering.
