Problem points Consider the following array which needs to be sorted in ascending order
using Quicksort:
a points Explain which pairs of elements are swapped during the st partitioning. Also,
show the content of the array at the end of the st partitioning.
b points Explain which pairs of elements are swapped during the nd partitioning. Also,
show the content of the array at the end of the nd partitioning.
Problem points Consider the following sorted array:
a points List the elements of the array that the binary search algorithm accesses when it
searches for Briefly justify your answer.
b points List the elements of the array that the binary search algorithm accesses when it
searches for Briefly justify your answer.
Problem points Determine whether or not each of the following statement is true. Also,
justify your answer rigorously using the BigO BigOmega, andor BigTheta definitions.
a pointsn is On
b pointsn
is Theta n
Problem points Express the time complexity in BigO notation of each of the following
cases assuming that the size of the input data ie the length of the given array is N Briefly
justify your answer. You do not need to apply the BigO definition ie fn is Ogn if there
exist positive constants c and n such that fn c gn for all n n to justify your expression
in BigO notation.
a points Best case of binary search
b points Worst case of selection sort
c points Best case of insertion sort
c points Worst case of insertion sort
d points Worst case of Quicksort assume that, when a portion of the array is partitioned,
the first element in that portion is chosen as the pivot
