Scala is a functional and object-oriented language ideal for data structures and concurrent programming. It offers multiple solutions to the 'Add Two Numbers' problem.
The approach focuses on iterating through linked lists, summing corresponding digits, and handling the carry for sums exceeding 9. It ensures no leading zeros.
Space complexity is O(n) as each sum digit requires a new node, leading to a proportional increase in space based on the result list's length.
