We learned about ArrayList and the process of boxing-unboxing. we explored memory type Stack vs Heap and how .NET calls the functions using stack-frame. We saw Generic List<T> class which avoids the boxing-unboxing operations. We got familiar with the LINQ API. finally we implemented a Stack data-type functions using List commands (behind the scenes)

More topics covered:

• • Garbage Collector (GC) – memory cleaning
  • Recursion methods – StackOverflow issues
  • Stack frame local variables
  • Typesafe
  • List<T>.Insert
  • List<T>.Count
  • List<T>.RemoveAt
  • List<T>.Clear
  • List implementation uses an Array
