Data structures performance comparison

Data structures and their uses
If algorithm A takes less time to solve the same problem than algorithm B, then algorithm A is considered better.
Another important factor in comparing two algorithms is the amount of memory required to solve a given problem.
The algorithm that requires less memory is considered better..
What is performance analysis in data structure?
Performance analysis helps us to select the best algorithm from multiple algorithms to solve a problem.
When there are multiple alternative algorithms to solve a problem, we analyze them and pick the one which is best suitable for our requirements..
Which data structure is faster?
With a hash table, you can access objects by the key, so this structure is high-speed for lookups.
Hash tables are faster than the arrays for lookups..
Which data structure is fastest?
Assuming you're talking some Set or Map or Array type data-structure.
Arrays are by far the fastest to “read” or “write”. 100ns upper bound even on TLB miss (assuming no swap file).
Obviously they are the most limiting (you need a dense numeric key set or you have 100 petabytes of RAM just to store 2 items)..
If algorithm A takes less time to solve the same problem than algorithm B, then algorithm A is considered better.
Another important factor in comparing two algorithms is the amount of memory required to solve a given problem.
The algorithm that requires less memory is considered better.
Selecting a proper data structure can have a remarkable effect on the efficiency of the final program.
In this paper it i s shown how one problem can be solved in several ways using several different data structures.
The efficiency of the programs depend on the data structures selected.

This is a comparison of the performance of notable data structures, as measured by the complexity of their logical operations. For a more comprehensive ListsMapsInteger keysPriority queues

Lists

A list or sequence is an abstract data type that represents a finite number of ordered values, where the same value may occur more than once

Maps

Maps store a collection of (key, value) pairs, such that each possible key appears at most once in the collection

Priority queues

A priority queue is an abstract data-type similar to a regular queue or stack. Each element in a priority queue has an associated priority. In a priority queue

Should you learn a data structure in an interview?

Sometimes interview questions explicitly mention a data structure, for example, “given a binary tree

” Other times it’s implicit, like “we want to track the number of books associated with each author

” Learning data structures is essential even if you’re just trying to get better at your current job

Let’s start with understanding the basics

What is a data structure?

Simply put, a data structure is a container that stores data in a specific layout

This “layout” allows a data structure to be efficient in some operations and inefficient in others

Your goal is to understand data structures so that you can pick the data structure that’s most optimal for the problem at hand

Why do we need Data Structures?

Why do data structures have different algorithms?

Each data structure has it’s own different way, or different algorithm for sorting, inserting, finding, …etc

This is due to the nature of the data structure

There are algorithms used with specific data structure, where some other can’t be used

The more efficient & suitable the algorithm, the more you will have an optimized data structure
