Write a program to create a hashed file that stores the records currently in the file "data_2013". Records should use the same fixed-length schema given previously, and should again be written in binary.
When inserting the records into your new file, they should be hashed on the ID attribute.
Using a static hashing approach, with the hash functionID % pageswhere pages is the number of pages in the file) to determine which "page" of the file the recordsshould be stored in. For simplicity (so that you do not need to worry about the possibility ofoverflow records), assume an average occupany of 80%. (Hint: as a first step, your programshould calculate the total number of pages that there will be in your file, based on the numberof records to be stored, the occupancy, and the pagesize parameter.) You should implement this hashing algorithm yourself.
What are the structures used in file-system implementation? Several on-disk and in-memory structures are used to execute a file system a. On-disk structure include P
Q. What do you understand by the term Binary Tree? What is the maximum number of nodes which are possible in a Binary Tree of depth d. Explain the terms given below with respect to
Binary Search Tree let three types of traversals by its nodes. They are: Pre Order Traversal In Order Traversal Post Order Traversal In Pre Order Traversal, we ca
In this unit, we will describe a data structure called Graph. Actually, graph is a general tree along no parent-child relationship. In computer science, Graphs have several applica
What is Efficiency of algorithm? Efficiency of an algorithm can be precisely explained and investigated with mathematical rigor. There are two types of algorithm efficiency
null(nil) = true // nil refer for empty tree null(fork(e, T, T'))= false // e : element , T and T are two sub tree leaf(fork(e, nil, nil)) = true leaf(

Q. Define a sparse matrix. Explain different types of sparse matrices? Show how a triangular array is stored in memory. Evaluate the method to calculate address of any element ajk
We might sometimes seek a tradeoff among space & time complexity. For instance, we may have to select a data structure which requires a lot of storage to reduce the computation tim
A Stack has an ordered list of elements & an array is also utilized to store ordered list of elements. Therefore, it would be very simple to manage a stack by using an array. Thoug
