Transcribed Image Text:11.) (a) Show how to Merge (not Mergesort) three ordered lists each of size n/3, with a total of at most
-n compare operations.
3
(b) Let's examine a new Merge sort algorithm, where parameter A in (A,n) is a list of numbers to be
sorted and n is the total length of list A.
Procedure mergeSort (A,n)::
if
Else
n=1 then return A
divide A into three equal size lists B, C, D,
B: mergesort(B,n/3)
C:=mergesort(C,n/3)
D:=mergesort(D,n/3)
return merge(B, C, D)
End.
Set up and solve a recurrence relation to analyze the worst-case number of operations of compares that
this version does.
