Which data structure is best for sorted data?

1- Arrays- Arrays are the most basic data structures for storing items of the same sort of data. Arrays can be used to store data in a tabular style as a simple application.

Which data structure is most appropriate for storing the user changes to the document?

1 Answer. Use an associative array, also called map or dictionary since different programming languages use different terms for the same data structure.

Which search is best and most efficient on sorted data set?

Interval Search: These algorithms are specifically designed for searching in sorted data-structures. These type of searching algorithms are more efficient than Linear Search method, as they repeatedly target the center of the search structure and divide the search space in 2 half. For Example: Binary Search.

Which is the best data structure for organizing and storing data?

1. Arrays. One of the simplest data structures, an array is a collection of items that are stored sequentially.

Which is the most efficient data structure?

An array is the simplest and most widely used data structure. Other data structures like stacks and queues are derived from arrays.

Which data structure provides elements storing in sorted order?

If you need a data structure that supports sorted order and lookup by index, you should definitely look into the order statistic tree, which is a data structure specifically designed to support exactly these operations.

Which data structure is most efficient to find the top?

Which data structure is most efficient to find the top 10 largest items out of 1 million items stored in file? Explanation: Min heap of size 10 is sufficient to find the top 10 largest items.

Which searching technique is efficient?

Binary search is a very fast and efficient searching technique. It requires the list to be in sorted order. In this method, to search an element you can compare it with the present element at the center of the list.

Which search algorithm is most efficient?

Binary search
Binary search is a more efficient search algorithm which relies on the elements in the list being sorted. We apply the same search process to progressively smaller sub-lists of the original list, starting with the whole list and approximately halving the search area every time.

What is the best data structure?

How do you store data structures?

1. Files. A computer file is used for storing information.
2. Lists. A list contains elements of one particular data type.
3. Array. An array is a data structure where the elements are identified by one or more indices.
4. Stacks. A stack is a data structure where elements are only inserted or deleted at the top.
5. Queue.

What are the most commonly used data structures in programming?

Let’s first list the most commonly used data structures, and then we’ll cover them one by one: 1 Arrays 2 Stacks 3 Queues 4 Linked Lists 5 Trees 6 Graphs 7 Tries (they are effectively trees, but it’s still good to call them out separately). 8 Hash Tables

Which algorithm is used to find the top 10 largest items?

Explanation: Min heap of size 10 is sufficient to find the top 10 largest items. The algorithm can be given as follows: 1. Create the min heap with first 10 items. 2. For each remaining item, check if 2.1 The item is greater than the item stored in the head of the min heap.

What is the use case for the stack data structure?

The stack is a last-in, first-out data structure. The developer can use the stack in the following use cases. Expression evaluation and syntax parsing. Finding the correct path in a maze using backtracking.

How stable is the sort() method in collections?

From the documentation of Collections.sort(List ): “This implementation is a stable, adaptive, iterative mergesort that requires far fewer than n lg(n) comparisons when the input array is partially sorted.” – Andy Thomas Jul 1 ’15 at 14:48
