Algorithms and Data Structures in Swift 5

Step up your Swift game with the ultimate guide to algorithms and data structures. Master coding challenges and write efficient, clean code like a pro!

Wondering how to write Swift code that’s not just functional but also efficient? You’re in the right place. We’ll dive deep into algorithmic thinking, the Big O notation, time complexity, and how to make your code work faster and smarter.

But that’s just the tip of the iceberg! We’ll dive into recursion, teaching you how to avoid common pitfalls. Then, we’ll explore Swift’s built-in collection types and when to use what. You’ll also learn about generics, so you can write versatile and reusable code.

Want to build custom data structures from scratch? We’ll cover that, too, from tuples and queues to deques and stacks. Not only will we look at what they are, but also how to implement them yourself.

And if you’re looking to sort data like a champ, we’ll tackle sorting algorithms from bubble sort to quicksort.

Secure Coding in C/C++

Ready to fortify your C/C++ code?

With over two decades in software development, I’ve seen my fair share of vulnerabilities.

I decided to create a course that uncovers the common security flaws in C/C++ code so you don’t repeat the mistakes I and my colleagues made.

We kick things off by spotlighting the usual suspects—security flaws that often sneak into C/C++ projects. You’ll get why secure coding isn’t a luxury; it’s a necessity. Then we dive into the nitty-gritty: input validation, memory management, error handling—you name it.

What You’ll Master

• Common security vulnerabilities in C/C++
• Input validation techniques
• Smart memory management
• Graceful error handling
• Secure file and data operations

Real-World Practice

We’re big on hands-on learning here. Through exercises and practical examples, you’ll know how to spot and fix security issues like a pro.

Why This Course?

• Clarified concepts, no jargon
• Q&A sessions for community learning
• Coding assignments to test your skills
