Problem 1. Assume we have an array A = {a1,...,an} of n elements, where it is guaranteed a %3D majority element exists. For example, (2,1,1} has a majority element 1. a. Describe a divide and conquer method to solve this problem. b. Write the run time as a recurrence sequence. c. Solve this recurrence sequence using any method introduced so far (expansion, generative function, master theorem).
