Question 1 (10 points) From Introduction to Algorithms ISBN 978 -0- 262 - 03293 -;3 Draw the recursion tree for the Merge-Sort procedure presented below on an array of 16 elements. Explain why memoization is ineffective in speeding up a good divide-and-conquer algorithm such as Merge-Sort. if p r then Merge-Sort (A,p,q); Merge-Sort(A,q + 1,r); Merge(A,p,q,r); end Algorithm 1: Merge-Sort(A,p,r) create arrays L [1..ni for i 1 to ni do and R1..n1]; end for j 1 to n2 do end for k p to r do if L z
