Complete Algorithms Complexity and Big O Notation Course


What you’ll learn

  • Algorithm Time and Space Complexity Evaluation

  • Interview Coding Tasks Review

  • Time Complexities Comparison

  • Mathematical Comparison of Functions

  • Typical Complexities Evaluation

  • Strings and Complexity Evaluation

  • Recursive Algorithms Complexity


  • Basic programming skills (you need to know how to write an “if-else” clause and a “for” loop)

To develop effective code, each developer needs to know how to evaluate the complexity of the algorithms.

The course “Big O Notation. Algorithms Complexity Evaluation.” in simple language explains the mathematics behind the complexity of algorithms, cases of complexity, the complexity of recursion, strings, amortized analysis and space complexity. In addition we solve 15 examples, some of which are found in interviews on Google, Facebook, Amazon.

We have reworked many books and articles to the most effective for perception and understanding form. As a result this course is independent by its nature and does not require studying of any additional materials. Basic programming skills is the only requirement to understand the course!

Important note: you can always pause the video and process into every aspect of the material in detail!

Who this course is for:

  • Beginners who want to understand from scratch to professional what complexity evaluation is
  • Developers of any level who want to pass an interview at companies such as Google, Facebook, Apple
  • Developers who want to learn how to write effective code
  • Beginner developers curious about time complexity evaluation and Big O Notation

Rating: 4.5 out of 5a year ago

This course is spot on for beginners needing a introduction to Big O and Complexity. Taking this course helps you understand why you should practice writing good code and the run time your algorithm has on your project. Great job!!!!!

  • Mathematical Comparison of Functions


  • Typical Complexities Evaluation


  • Addition and Multiplication


  • Strings and Complexity Evaluation


  • Recursive Functions Complexity
