You receive strings one by one from a stream. After each insertion, you must output: the oldest string that has appeared exactly once so far If no such string exists,

**return** ""

**Example** Stream: a, b, a, c, b, d After each insert: insert a → oldest non-repeating = a insert b → a insert a → b insert c → b insert b → c insert d → c Output: a, a, b, b, c, c
