Release Date: 2017-09-25 // over 6 years ago

  • Swift 4.0 is now officially released! As a result, The Swift Algorithms project has been updated to reflect this new standard.

    🔄 Change Summary

    The relative stability of Swift 4.0 has allowed an opportunity refine many areas of the code base. Notable updates include:

    • 🆕 New examples of code Memoization and Dynamic Programming
    • 🆕 New non-recursive Binary Search Tree Algorithm (BST)
    • 🆕 New contains() method for BST's.
    • 🆕 New generic min/max Heap Algorithm
    • 🆕 New unit test cases for evaluating Fibonacci and Heap Algorithms
    • subscript syntax applied to Trie and Linked List algorithms
    • 👌 Support for new Swift-based Array.swapAt function
    • Limited use of Implicit Unwrapped Optionals (IUO's)

    Existing Swift 3.0 followers should study the new Swift 4.0 BST Algorithm. To simulate a call stack often employed in recursive processes, this model uses a custom Stack data structure in conjunction with inout variables.
