   • BBubble sort: sort the list and then take the last element.
   • CRecursive function that calls itself on the first half and second half of the list.
   • DLinear search: iterate through the list, keeping track of the largest value seen so far.

   A program reads a configuration file from disk. If the file does not exist, the program should display a user-friendly message and exit gracefully, rather than crashing with a stack trace. Which error handling technique should the developer use?
