Answer:

2 times as many items can be uniquely identified

Explanation:

Option 'C' is the answer. because

if we use 6 bit binary sequence

then

No. of Unique address will be = 2 ^ 6  = 64

as we increase the bit by 1. Now total bits are 7.

so

No. of Unique address for 7 bit Sequence = 2 ^ 7  = 128

So,

128 is double of 64, that is 2 times greater value than 64.

Define a function typeHistogram that takes an iterator ""it"" (representing a sequence of values of different types) and builds
Alexeev081 [22]

Answer:

def typeHistogram(it,n):

   d = dict()

   for i in it:

       n -=1

       if n>=0:

           if str(type(i).__name__) not in d.keys():

               d.setdefault(type(i).__name__,1)

           else:

               d[str(type(i).__name__)] += 1

       else:

           break

   return list(d.items())

it = iter([1,2,'a','b','c',4,5])

print(typeHistogram(it,7))

Explanation:

  • Create a typeHistogram function that has 2 parameters namely "it" and "n" where "it" is an iterator used to represent a sequence of values of different types while "n" is the total number of elements in the sequence.
  • Initialize an empty dictionary and loop through the iterator "it".
  • Check if n is greater than 0 and current string is not present in the dictionary, then set default type as 1 otherwise increment by 1.
  • At the end return the list of items.
  • Finally initialize the iterator and display the histogram by calling the typeHistogram.

You must keep track of some data. Your options are: (1) A linked-list maintained in sorted order. (2) A linked-list of unsorted
ladessa [460]

Answer:

Question was incomplete and continued the question

For each of the following scenarios, which of these choices would be best? Explain your answer.

BST

Sorted Array

Un-sorted Array

a) The records are guaranteed to arrive already sorted from lowest to highest (i.e., whenever a record is inserted, its key value will always be greater than that of the last record inserted). A total of 1000 inserts will be interspersed with 1000 searches.

b) The records arrive with values having a uniform random distribution (so the BST is likely to be well balanced). 1,000,000 insertions are performed, followed by 10 searches.

Explanation:

Answer for a: Un-sorted array or Un-sorted linked list : as mentioned in the question itself that the records are arriving in the sorted order and search will not be O(log n) and insert will be not be O(n).

Answer for b : Un-sorted array or Un-sorted linkedlist : Number of the items to be inserted is already known which is 1,000,000 but it is very high and at the same time search is low. Unsorted array or Unsorted linked list will be best option here.
