problem

Greetings

I have seen and read the reviews for the above problem, and made the modifications suggested. I did see the comment on using LINQ, I am learning how to use them and don't fully understand it yet. I successfully submitted my answer to LeetCode, but I would like a review to see what else I can do to improve the code. I noticed the code uses more memory than most submissions on LeetCode and I wonder if I can find out why here. Problem statement:

My code is based on a tutorial I watched. While it was in Java, I typed my code in C#. It recursively calls the method that looks into the objects of a Dictionary and concatenates the data inside them in the desired format.

I am new to programming so I looked up stuff online and made some assumptions on equivalent data structures in C#.

For example, the original code used a HashMapHashMap, and saw a recommendation online to used Dictionary<T, T>Dictionary<T, T> in C#.
