Inputs contain valid strings or integer arrays. Return an empty string or empty array when no characters or duplicates exist.

Constraints

  • value is either a string or an array of integers
  • 0 <= len(value) <= 10^5
  • For array input, duplicate values must appear once in first-detection order
