For a project, I need to merge two dictionaries: {'x': 10, 'y': 20} and {'y': 25, 'z': 30}. Also, I have a complex sentence 'Analyzing the data for insights can be challenging but rewarding.'. Can you count the vowels in this sentence and find the maximum subarray sum for the list [10, -5, 15, -3, 12, -8]?
