What is stacks in data structure?
Stack is a data structure which is closed at one end. last in first outhi
Can implement circular lists using stack?
No. A stack is a data structure that allows insertion and removal at the top. A circular list allows insertion and removal anywhere in the list. The two types of data structure are too different to be reasonably implementable in terms of each other.
What is first in first out data structure?
QUEUE is the first in first out (FIFO) data structure. It is a linear data structure in which insertion of an element is done from rear end of a list and deletion of an element is done from front end of a list. For example- people in queue waiting for bus.
What are the applications data structure?
Data structures could be used to implement an efficient database. Linked lists for example will optimize insertion and deletion for ordered lists.
Which data structure allows deletion from both ends and insertion only from one end?
Deque double ended queue
What is the time complexity of operations in a hashset data structure?
The time complexity of operations in a hashset data structure is typically O(1) for insertion, deletion, and search operations. This means that these operations have constant time complexity, regardless of the size of the hashset.
What are the properties and operations of a minimum binary heap data structure?
A minimum binary heap is a data structure where the parent node is smaller than its children nodes. The main operations of a minimum binary heap are insertion, deletion, and heapify. Insertion adds a new element to the heap, deletion removes the minimum element, and heapify maintains the heap property after an operation.
Who is best merge sort or insertion sort?
Merge sort is good for large data sets, while insertion sort is good for small data sets.
What is the significance of the head in a linked list data structure?
In a linked list data structure, the head is the starting point that points to the first node in the list. It is significant because it allows for traversal of the list by providing access to the first element, enabling operations such as insertion, deletion, and searching.
What are the advantages of data structure?
The tree structure is useful because it easily accommodates the creation and deletion of folders and files.
What are the subject-matters of data structure?

How do you insert data in middle of file in java?
One way to do it would be as follows: * Read the entire file to a String variable * Write the data before the insertion point * Write the data to be inserted * Write the data after the insertion point Probably the following would be more efficient: * Read the part of the file after the insertion point, to a String variable * Write the data to be inserted * Write the data after the insertion point Perhaps some classes have methods that can automate this, from the point of view of the programmer. But if you want to INSERT something, it's unavoidable to have the overhead of reading the data after the insertion point, and writing it back again. This assumes you use a text file; when working with a database, there are other, usually more efficient, options.
