Q1. A. What is time complexity and space complexity? Analyze the performance   of   Binary   Search   using   time   and   space complexities. 5

Ans:

An algorithm is a step by step procedure for solving a particular problem. One major purpose of this text is to develop efficient algorithms for the processing of our data. The efficiency of the algorithm is depending on the time and space it uses. The complexity of an algorithm is the function which gives the running time and/ or space in terms of the input size. Each of our algorithms will involve a particular data structure. The data structure which we choose will depend on many things, including the data and   the   frequency   with   which   various   data   operation   are   applied. Sometimes the choice of data structure involves a time- space tradeoff by increasing the amount of space for storing the data, one may be able to reduce the time needed for processing the data, or vice versa. So, we may not always be able to use the

B.            Write an algorithm/pseudocode to delete the node following a given node in linked list.           5

Ans:

Deletion Algorithm: We have algorithms for deletion from linked list in various situations. The first one deletes the node following a given node and the second one deletes the node with a given ITEM of information.All of our deletion algorithms will return the memory space of the deleted node N to the beginning of the AVAIL list. Accordingly, all of our algorithms will include the following pair of assignments, where LOC is

Q3A. Explain the postorder traversals on binary tree.          5         

Ans (a).

Postorder traversals on binary tree:

In  postorder  traversal,  traversal  starts  with  the  left  most  subtree  then proceeds with right sub tree and print the parent of those nodes.

B.            What  is  a  binary  search  tree?  What  are  the  common operations that can be performed on binary search trees?      5         

Ans (b).

Binary Search Tree: T is a binary tree. Then T is called binary search tree if each node of n of T has the following property. The value at n is greater than every value in the left subtree of n and is less than every value in the right subtree of n. We can say one of the most important data structure is binary search tree. This enables one to search for and find an element with an average running time f(n)=O(log2 n). It

Q4 A. What  is  static  memory  allocation  and  dynamic  memory allocation?      5

Ans (a).

Static Memory Allocation: Static Memory Allocation, also known as Compile-time Memory Allocation, is used for the allocation of memory during the process of compilation of data in a fixed size. The compiler allocates memory

5. What is an AVL tree. How do you perform search operation in an AVL tree? Explain with the help of an example.        10      

Ans (5).

AVL tree: An  AVL  tree  is another  balanced binary search tree  named  after their inventors, Adelson-Velskii and Landis. An empty binary tree is an AVL tree. A non empty binary tree T is an AVL tree if given TL and TR to be the left and right subtrees of T and h(TL) and h(TR) to be the heights of subtrees TL and TR

Q6  A. Give algorithm/pseudocode for DFS. Demonstrate DFS using suitable example?   5       

Ans (a):

Depth first search (DFS) algorithm starts with the initial node of the graph G, and then goes to deeper and deeper until we find the goal node or the node which has no children. The algorithm, then backtracks from the dead end towards the most recent node that is yet to be completely unexplored.

B.            Design an algorithm/ pseudocode for selection sort.          5         

Ans (b):

Selection sort: Selection sort is one of the sorting techniques that is typically used for sequencing small lists. It starts by comparing the entire list for the lowest item and moves it to the #1 position. It then compares the rest of the list for the next-lowest item and places it in the #2 position and so on until all items

b. What is a Process Control Block? What information is stored in it?   5+5      10

Ans (a).

Virtual Environment & Machine Aggregation: A virtual environment (otherwise referred to as Virtual private server) is another kind of a virtual machine. In fact, it is a virtualized environment for running user-level programs (i.e. not the operating system kernel and drivers, but applications). Virtual environments are created using the software implementing operating system-level

Q4 a.  What is Page replacement? Discuss it’s FIFO algorithm with an example.

b.  What is Thrashing? What are its causes?          5+5      10

Ans (a):

Page Replacement: Initially, execution of a process starts with none of its pages in memory. Each of its pages will have page fault at least once when it is first referenced. But it may so happen that some of its pages are never used. In such a case those pages which are not referenced even once will never be brought into memory. This saves load time and memory space. If this is so, the degree of multi-programming can be increased so that more ready processes can be loaded and executed. Now, we may come across a situation wherein all of sudden, a process hitherto not accessing certain pages starts accessing those pages. The degree of multi-

b. What are I/O Control Strategies?            5+5      10

Ans (a).

File Access Methods: Information is stored in files. Files reside on secondary storage. When this information is to be used, it has to be accessed and brought into primary main memory. Information in files could be accessed in many ways. It is usually dependent on an application. Access

Q2A) Explain Operating leverage and financial leverage with their application.  5+2+2+1     

B) Shivam Ltd. has Total Capital of ₹ 60 Lakh. Out of which ₹ 20 Lakh is Equity Capital and ₹ 40 lakh is debt. Rate of interest payable on debt is 12%. The Sales Revenue of YZ Ltd is ₹ 100 lakh. Variable cost is 20% of Sales revenue and ₹ 30 lakh is the fixed cost of operation.                  

Required: Calculate Financial, Operating and Combined Leverages.               

Ans 2a.

Operating Leverage

Operating leverage arises due to the presence of fixed operating expenses in the firm’s income flows. It has a close relationship to business risk. Operating leverage affects business risk factors, which can be viewed as the uncertainty inherent in estimates of future operating income.

The operating leverage takes place when a change in revenue produces a greater change in Earnings Before Interest and Taxes (EBIT). It indicates the impact of changes in sales on operating income. A firm with a high operating leverage has a relatively greater effect on EBIT for small changes in sales. A small rise in sales may enhance profits considerably,
