What method calls itself repeatedly?
Recursion is the process of defining something in terms of itself. It allows us to define method that calls itself repeatedly until it meets some base case condition.What is recursive technique?
Recursion is the technique of making a function call itself. This technique provides a way to break complicated problems down into simple problems which are easier to solve.What is recursion and example?
Recursion is the process of defining a problem (or the solution to a problem) in terms of (a simpler version of) itself. For example, we can define the operation "find your way home" as: If you are at home, stop moving. Take one step toward home.- Recursion is a method in C++ which calls itself directly or indirectly until a suitable condition is met. In this method, we repeatedly call the function within the same function, and it has a base case and a recursive condition.
1. The correct choice of data structure allowsmajor improvements in program Efficiency. ( )
2. A data structure is the organization of data in a computer̓s memory or in a disk file. ( )
3. In Java, an algorithm is usually implemented by a class method. ( )
4. A binary search can be applied to an ordered array.( )
5. Linear searches don't require time proportional to the number of items in an array.( )
6. Sorting involves comparing the keys of data items in the array and moving the
items (actually, references to the items) around until they̓re in sorted order. ( )7. The bubble sort is the least efficient, but the simplest, sort. ( )
8. A queue allows access to the first item that was inserted. ( )
9. A stack allows access to the last item inserted. ( )
10. Each Link object contains data and a reference, often called next, to the next link in the ist. ( )
11. A double-ended list allows insertion at the end of the list. ( )
12. A doubly linked list permits backward traversal and deletion from the end ofthe list. ( )
13. A new link can be inserted before or after a link with a specified key value, following
a traversal to find this link. ( )14. A double-ended list maintains a pointer to the last link in the list, often called last,
as well asto the first. ( )15. Some values of its arguments don't cause a recursive method to return without calling
itself.This is called the base case.( )16.A recursive approach may be inefficient. If so, it can sometimes be replacedwith a simple
loop or a stack-based approach.( )17. A recursive method calls itself repeatedly, with different argument values each time. ( )
18. Both triangular numbers and factorials can't be calculated using either arecursive method
or a simple loop. ( )
19. Edges are most commonly represented in a program by references to a node̓schildren
(and sometimes to its parent). ( )
20. Graphs can represent many real-world entities, including airline routes,
electrical circuits, and job scheduling.( ) Course no : SWEN3411 College of Engineering Student No: __________ Course tile:Data structure final Exam Student Name: _________ Exam Time: 2 Hour 1st Semester 2018/2019 Date: 17.01.2019 No of Questions: Total Grade: 100 Try to Answer All QuestionsOpen Book: No

1) The maximum number of elements that must be examined to complete a
binary search in an array of 200 elements is a. 200. b. 8. c. 1. d. 13.2) A binary tree is a search tree if
a. every non-leaf node has children whose key values are less than (or equalto) the parent. b. every left child has a key less than the parent and every right child has akey greater than (or equal to) the parent. c. in the path from the root to every leaf node, the key of each node isgreater than (or equal to) the key of its parent. d. a node can have a maximum of two children.3) A subtree of a binary tree always has
a. a root that is a child of the main tree's root. b. a root unconnected to the main tree's root. c. fewer nodes than the main tree. d. a sibling with the same number of nodes.4) Suppose you push 10, 20, 30, and 40 onto the stack. Then you pop three items. Which one
is left on the stack? a. 40 b.10 c. 20 d. 305) Suppose you insert 15, 25, 35, and 45 into a queue. Then you remove three items.
Which one is left?
a. 45 b. 35 c. 15 d. 256) When you create a reference to a link in a linked list, it
a. must refer to the first link. b. must refer to the link pointed to by current. c. must refer to the link pointed to by next. d. can refer to any link you want.7) The bubble sort algorithm alternates between
a. comparing and swapping. b. moving and copying. c. moving and comparing. d. copying and comparing.8) Computer sorting algorithms are more limited than humans in that
a. humans are better at inventing new algorithms. b. computers can handle only a fixed amount of data. c. humans know what to sort, whereas computers need to be told. d. computers can compare only two things at a time.9) The disadvantage of mergesort is that
a. it is not recursive. b. it uses more memory. c. although faster than the insertion sort, it is much slower than quicksort. d. it is complicated to implement.10) Finding a node in a binary search tree involves going from node to node, asking
a. how big the node's key is in relation to the search key. b. how big the node's key is compared to its right or left children. c. what leaf node we want to reach. d. what level we are on.ThirdQuestion(60)
1) fill in the array (Heap) as showing in the graph (3 marks)
2) Implement a binary tree
a. You must have a recursive insert method inside the Node class b. You must have 3 method to traverse the array (in order, pre order, and post order) c. You must have a search method3) If a stack is implemented using an array then write the pop method for that stack (2 marks)
4) Write a method called copyStack that copies the content of one stack into another. The function must have
two arguments of type stack, one for the source stack and one for the destination stack. The order of two
stacks must be identicalP.S : assume that you have stack class with all of its method like pop, push, peak, and isEmpty so no need to
write the stack implementation.5) Assume that you have an array with multiple integer values something like this
int [ ] arr = {2, 1, 10, 8, 3, 10, 5, 10};First you should implement a method the sort the array using selection sort and the return the new sorted array
Second you should you use the sorted array to find the second biggest number in the sorted arrayNote͗ you should assume that you can't see the elements of the array so please don't use something like (the biggest
number - 3) to find the second biggest number or you will lose some of your marksBonus: Write some code to print the following without using any form of if statement or ternary operator
This is infinite so it won't stop
