– DATA STRUCTURE QUIZ REVIEW DETAILS & REVIEW DETAILS This short quiz
covers the Data Structures unit. All
notes. All work. REVIEW
b) The
traditional method used to add an element to a stack is called
_______________ (although
Java also supports the add method.). c) In Java, the
method used to get and remove an element from a queue is called
_______________. Traditionally, it is often called dequeue. d) The method
used to get and remove an element from a stack is called _______________. e) FIFO
refers to ____________ ___________ ____________ ____________. It is the same as LILO. f) FILO
refers to ____________ ___________ ____________ ____________. It is the same as LIFO. g)
_______________ is the type of data structure that is FIFO. h)
_______________ is the type of data structure that is FILO. i) ____________ is a data structure
where all elements are stored together sequentially in memory. This structure cannot be resized. j) A(n)
____________ is a linear data structure that stores elements in different
nodes. Each node is stored in a
different location in memory. This
structure can be resized efficiently. k) A(n)
______________ is like a normal array but with the ability of being
resized. It could be implemented using
an array or a linked list. l) A data
structure that allows you to add and remove elements only at the one end of
it is called _____________. m) A data
structure that allows you to add elements at one end and get/remove from the
other end is called _______________. n) A data
structure's efficiency is measured by both the ______________ and the
_______________ to manipulate the structure. p) Java
_________________ is the framework that contains many different
implementations of data structures including lists, sets and maps. q) With
regards to Data Structures, ADT stands for _______________ ________________
________________. r) A(n)
__________________ is a data structure that stores both a key and value. The
key is used to access the value. It is
also called an associative array. t) Java
implementations of Map ADTs include ________________ and _______________. u) Java
implementations of Set ADTs include ________________ and ________________. v) The
enhanced for loop can be used with data structures that implement the
____________ interface. y) Both the Stack and Queue implementations that we
looked at have a __________ method that allows you to see the element that
could be popped or polled next but doesn’t actually remove the element from
the structure.
QUESTION 2
QUESTION 3 What will the
following code output: a) lili.add(5); lili.add(4); lili.add(0); System.out.println(lili); b) ArrayList<Integer>
al = new ArrayList<Integer>(); al.add(5); al.add(0,4); al.add(7); System.out.println(al); c) Stack<String> stak = new Stack<String>(); stak.push("Luke"); stak.push("Leia"); stak.push("Han"); stak.push("Yoda"); stak.pop(); System.out.println(stak); d) Queue<String> q = new LinkedList<String>(); q.add("Vader"); q.add("Kylo"); q.add("Palpatine"); q.remove(); q.remove(); System.out.println(q); e) TreeSet<Integer>
s = new TreeSet<Integer>(); s.add(5); s.add(3); s.add(2); s.add(1); s.add(5); System.out.println(s.size()); QUESTION
4 Consider
the following drawing of a linked list. a)
Alter the drawing to insert a Node at the end containing the
value 35. b)
Alter the original drawing to insert a Node at the beginning
containing the value 30. c)
Alter the original drawing to insert a Node after the middle
node. d)
Alter the original drawing to remove the middle node from the
list. QUESTION 5 Considering
Linked Lists and Dynamic Arrays, which is more efficient to a)
Look up the value at any element i b)
Inserting a value at the end of the collection c)
Inserting a value at the start of the collection d)
Removing a value from a location i
in the collection e)
Going through the collection one element at the time to
calculate the total of all values
Explain
two different strategies on how to implement a dynamic array. You are essentially being asked to give two
strategies on how to deal with inserting/deleting into an array. |
