Part 2) Determine what lines of code would be required to complete each code fragment.

21. The following function, checkOrdered(), takes in a list of numbers and has to check if    those numbers are ordered in ascending order and return a boolean variable indicating whether or not the list is sorted. For example, checkOrdered([1, 3, 7]) should return True, and checkOrdered([4, 8, 5]) should return False. Three lines in this function are    missing. From the options listed below, determine which lines are needed to complete the function.

def checkOrdered(data):

prev = data[0]

_______________                        # blank 1

_____________                  # blank 2

return False

__________                        # blank 3

return True

Possible Lines

i.           for d in data:

ii.          for d in data[1:]:

iii.         while d in data:

iv.         if prev > d:

v.          if prev < d:

vi.         while prev > d:

vii.        d = prev

viii.       prev = d

ix.         prev += 1

a.   i, iv, vii

b.   ii, iv, viii

c.   i, v, ix

d.   iii, v, vii

e.   ii, v, viii

22. The following function, findMaximum(), takes in a dictionary in which each value is a list of positive numbers. Note that each list could be a different length. The function is supposed to find the highest number found in any of the dictionary's lists and return      that highest number. Three lines in this function are missing. From the options listed below, determine which lines are needed to complete the function.

def findMaximum(dictionary):

highest = -1

_______________                           # blank 1

_____________                     # blank 2

for d in alist:

if d > highest:

__________        # blank 3

return highest
