id=11^^name=smith, ^peter^^city=Chicago

id=12^^name=mcdonalds, julie^^city=NY=C

Things to consider:

2. = is the delimiter within a key value pair.

3. The VALUE can be NULL but the KEY cannot be NULL

4. There could be a partial delimiter or multiple delimiters in a VALUE. In these cases, remove ^ and = from values

Expected output format:

id|name|city

bel|james|paris

smith|peter||Chicago

mcdonalds|julie|NYC
