## What is the data structures and algorithms?

A data structure is a named location that can be used to store and organize data. And, an algorithm is a collection of steps to solve a particular problem. Learning data structures and algorithms allow us to write efficient and optimized computer programs.

### What is DS and why it is required?

Data Structure can be defined as the group of data elements which provides an efficient way of storing and organising data in the computer so that it can be used efficiently. Some examples of Data Structures are arrays, Linked List, Stack, Queue, etc.

**How long does it take to master DSA?**

DSA requires a significant investment of time and effort. It can take you anywhere from 4-8 months to truly master it. The important thing is to put in the time and effort.

**What are types of DS?**

When we think of data structures, there are generally four forms:

- Linear: arrays, lists.
- Tree: binary, heaps, space partitioning etc.
- Hash: distributed hash table, hash tree etc.
- Graphs: decision, directed, acyclic etc.

## Which programming language is best for DSA?

Most competitive programmers use C++ because of its efficiency for DSA. That being said, the language is just a medium and any language that you are affluent with is appropriate for you to implement DSA.

### Why is DSA so important?

Why DSA is important? DSA plays a very important role in reducing the time complexity of the code. A problem might have several approaches, but you must pick the optimized one in order to stand out of the crowd. You must be able to write a code which takes less time to execute for any problem statement given.

**Which language is best for algorithm?**

C++ is the best language for not only competitive but also using to solve the algorithm and data structure problems . C++ use increases the computational level of thinking in memory , time complexity and data flow level.

**What is ADT in data structure?**

An ADT is a mathematical model of a data structure that specifies the type of data stored, the operations supported on them, and the types of parameters of the operations. An ADT specifies what each operation does, but not how it does it. Typically, an ADT can be implemented using one of many different data structures.
