In this section, we will discuss about Sequential file organization. Sequential files have data records stored in a particular sequence. A sequentially organized file might be stored on either a serial-access or a direct-access storage medium.
Structure
In order to provide the 'sequence' required, a 'key' has to be defined for the data records. Generally a field whose values can uniquely identify data records is chosen as the key. If a single field cannot fulfill this criterion, then combination of fields can serve like a key.
What are circular queues? Circular queue: Static queues have a very large drawback that once the queue is FULL, even though we erase few elements from the "front" and relieve
In internal sorting, all of the data to be sorted is obtainable in the high speed main memory of the computer. We will learn the methods of internal sorting which are following:
The pre-order and post order traversal of a Binary Tree generates the same output. The tree can have maximum One node
Using Assertions When writing code, programmer must state pre- and subtle post conditions for public operations, state class invariants and insert unreachable code assertions a
Describe Binary Search Tree (BST)? Make a BST for the given sequence of numbers. 45, 36, 76, 23, 89, 115, 98, 39, 41, 56, 69, 48 Traverse the obtained tree in Preorder, Inord
It offers an effective way to organize data while there is a requirement to access individual records directly. To access a record directly (or random access) a relationship is
What is AVL Tree? Describe the method of Deletion of a node from and AVL Tree ?
difference between recursion and iteration
A BST is traversed in the following order recursively: Right, root, left e output sequence will be in In Descending order
Q. Write down the algorithm which does depth first search through an un-weighted connected graph. In an un-weighted graph, would breadth first search or depth first search or neith
