Which data structure allows us to add an element at one end and remove the element from the other end?

What is Stack Data Structure? Stack is an abstract data type with a bounded(predefined) capacity. It is a simple data structure that allows adding and removing elements in a particular order.

In which of the following data structures can you remove an element from anywhere in list?

A Static Queue is a queue of fixed size implemented using array. Singly Linked List: A linked list is also an ordered list of elements. You can add an element anywhere in the list, change an element anywhere in the list, or remove an element from any position in the list.

In which data structure we can delete insert element easily?

A linked list provides efficient insertion and deletion of arbitrary elements. Deletion here is deletion by iterator, not by value. Traversal is quite fast. A dequeue provides efficient insertion and deletion only at the ends, but those are faster than for a linked list, and traversal is faster as well.

Which data structure will give a sorted set of elements if you are only allowed to remove top element from the data structure?

A stack is an abstract data type that specifies a linear data structure, as in a real physical stack or piles where you can only take the top item off the stack in order to remove things.

In which data structure you can insert data at any end but can remove a data at only one end?

  1. Stack:- A stack is a linear data structure in which elements can be inserted and deleted only from one.
  2. side of the list, called the top.
  3. called push operation, and deletion of an element from the stack is called pop operation.
  4. always keep track of the last element present in the list with a pointer called top.

Which is the best data structure to add and remove element frequently at rear end of the list?

Probably the best data structure for this purpose would be a deque implemented with a dynamic array, which is basically an ArrayList that starts adding elements to the middle of the internal array instead of the beginning.

Which of the following data structure can delete elements?

Answer: Answer:Deleting the top element of a stack is O(1), which is valid because you only have access to the top of the stack. Hash tables also have amortized O(1) deletion for any element of the table.

What is an element in data structure?

The fundamental data structure in a data processing system. Any unit of data defined for processing is a data element; for example, ACCOUNT NUMBER, NAME, ADDRESS and CITY. A specific set of values or range of values may also be part of the definition.

What data structure should be used if we have to implement insert and delete functions in a text editor?

A Rope data structure is a tree data structure which is used to store or manipulate large strings in a more efficient manner. It allows for operations like insertion, deletion, search and random access to be executed faster and much more efficiently in comparison to a traditional String.

What data structure would you recommend for ordered and sorted data?

Which data structure would you recommend for ordered and sorted data? Ans. TreeSet and TreeMap are used for maintaining sorted elements.

Which data structure allow deleting data element from front and inserting at rear?

Queue allows insertion of data elements from rear and deletion from front.

Which of the following structure allows elements to be inserted or deleted only from one end?

Stack A stack is a linear data structure in which elements can be inserted and deleted only from one side of the list, called the top.
