How many times will count++ execute when i = 3, in this pseudocode?
int count = 0;
int N = 4;
for (int i = 0; i < N; i++)
for (int j = 0; j < i; j++)
count++;

What is the most efficient data type to use for this data set of a fixed
size in Java?
a = [0, 0, 1, 4, 7, 16, 31, 64, 127]
Array

What is true about garbage collection?
It reclaims memory from data structures implemented using linked
allocations.
What is true about a data structure implemented using linked
allocation?
Storage is allocated using pointers to new locations as needed.
What are the array elements corresponding to the mid-values in the
first and second iterations of a binary search in an array arr = {45, 77,
89, 90, 94, 99, 100} and key = 100?
90 and 99
What is the effect on the object Computing regarding garbage
collection?
Computing obj = new Computing(); obj = null;
It is automatically available for garbage collection.

What are the mid-values in the first and second levels of recursion in
this binary search?
int arr = {46, 76, 89, 90, 94, 99, 100} and key = 99
90 and 99
Which data set is represented using the dictionary data type?
A set of students and their test scores
What is a characteristic of keys in an associative dictionary data type?
They are unique and immutable.
Which method can be used to take a value out of a dictionary?
D1[key].remove(value)
Given this data dictionary in Python:
, Page 4 of 74
dict = {'white':0x0000, 'black':0x1111}
Which command/function generates the output ['white','black']?
dict.keys()
Items were added sequentially in this stack starting with 'ham':
'sausage'
'toast'
'eggs'
'ham'
What is the correct order of contents after the push operation is
performed with the value 'bacon'?
'bacon'
'sausage'
'toast'
'eggs'
'ham'
