Data Structures and Algorithms Quick Revision Best Guide

Here is a complete guide of Data Structures and Algorithms Quick Revision for students and Aspirants who wants to appear for coding interviews.

Data Structures and Algorithms Quick Revision

These pages give detailed tutorials describing various data structure types. Data structures provide an efficient way to store data on any computing system. You will find several articles about each information structure here.


Data Structures – Asymptotic Analysis

Asymptotic analysis is the process of calculating the running time of an algorithm in mathematical units to find the program’s limitations, or “run-time performance.” The goal is to determine the best case, worst case and average case time required to execute a given task. While not a method of deep learning training, Asymptotic analysis is a crucial diagnostic tool for programmers to evaluate an algorithm’s efficiency, rather than just its accuracy.

Data Structures – Algorithms Basics

Space Complexity

The space complexity of an algorithm or a computer program is the amount of memory space required to solve an instance of the computational problem as a function of characteristics of the input. It is the memory required by an algorithm until it executes completely.

Algorithm analysis

Analysis of algorithms is the determination of the amount of time and space resources required to execute it.

Need for Data Structure

The need of Data Structure includes efficiency and reusability. Data structure provides a way of organizing, managing, and storing data efficiently. With the help of data structure, the data items can be traversed easily.

Execution Time Cases

The time spent by the job actively using processor resources is its execution time. The execution time of each job instance from the same task is likely to differ. Execution times are of interest to real-time systems designers usually in the context of worst-case execution times.

Characteristics of an Algorithm

  • Unambiguous
  • Input
  • Output
  • Finiteness
  • Feasibility
  • Independent

Tell me the best way to write algorithms?

  • Obtaining a description of the problem.
  • Analyzing the problem.
  • Developing a high-level algorithm.
  • Refining the algorithm by adding more detail.
  • Reviewing the algorithm.

Algorithm Complexity

  • Algorithmic complexity is a measure of how long an algorithm would take to complete given an input of size n.

Time Complexity

  • Time required to analyze the given problem of particular size is known as the time complexity

Characteristics of a Data Structure

  • Linear
  • Non-Linear
  • Static
  • Homogenous
  • Non-Homogenous
  • Dynamic
  • Time Complexity
  • Space Complexity

Local environment setup

Setting up local development environment.
