2. a. Write a pseudocode for a divide-and-conquer algorithm for finding values

of both the largest and smallest elements in an array of n numbers.

b. Set up and solve (for n = 2k) a recurrence relation for the number

of key comparisons made by your algorithm.

c. How does this algorithm compare with the brute-force algorithm for

this problem?
