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.
Explain an efficient way of storing a sparse matrix in memory. A matrix in which number of zero entries are much higher than the number of non zero entries is called sparse mat
Q. Give the algorithm for the selection sort. Describe the behaviours of selection sort when the input given is already sorted.
The advantage of list over Arrays is flexibility. Over flood is not a problem until the computer memory is bushed. When the individual record are quite large, it may be difficult t
Assertions and Abstract Data Types Even though we have defined assertions in terms of programs, notion can be extended to abstract data types (which are mathematical entities).
explain implementation of circular queue insert,delete operations
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
merge sort process for an example array {38, 27, 43, 3, 9, 82, 10}. If we take a closer look at the diagram, we can see that the array is recursively divided in two halves till the
In order to get the contents of a Binary search tree in ascending order, one has to traverse it in In-order
Q . Write down the non-recursive algorithm to traverse a tree in preorder. Ans: T he Non- Recursive algorithm for preorder traversal is written below: Initially i
RGB Model The RGB model is based on the assumption that any desired shade of colour can be obtained by mixing the correct amounts of red, green, and blue light. The exact hues
