Question: Let  be a sequence of  n characters (n > 1). Problem: We want to determine if contains the character string "ab" ('a' immediately followed by 'b').  

a) You have to solve the problem with an algorithm, following the "divide and conquer" approach. First you must clearly describe using English phrases the idea of your algorithm, then write pseudocode for your algorithm. The clarity and efficiency of your algorithm is taken into consideration when correcting.

b) Do the worst-case analysis of your algorithm using the input size n, and counting the number of times the algorithm compares two characters. In your analysis, find the recursion relation for the worst-case case of W(n), and resolve that relationship.
