Algorithms: Number of Islands Problem in Swift
Hello guys and girls, Leo here. Today we’ll solve a leetcode problem called “The Number of Islands” using DFS. I know it’s been a while since we don’t solve any algorithm problem so today we’re continuing the algorithm series. Let’s code! Number of Islands Problem – Using DFS to solve Given a 2d grid map of […]
Trie in Swift, the Autocorrect Structure
Hello ladies and gentlemen, Leo here. Today we’ll study a tree-like data structure called Trie in Swift. It’s a special type of tree and its main use in the modern world is the core of autocorrect(autocomplete) algorithms. Will be a great journey into this amazing data structure. At the end of the article, you’ll know exactly what […]
Functional Programming and Shopping Cart Problem in Swift
Hello ladies and gentlemen, Leo here. Today we will explore some Functional Programming in Swift. Functional programming is a programming paradigm that has some really cool ideas. For example, functions are first-class citizens, which means that you can do everything you could do with any other type like Int, you can do with a function like […]

The challenge is here: The Challenge Let’s go! The problem: Compare and update the inventory stored in a 2D array against a second 2D array of a fresh delivery. […]
Algorithms: Find the Symmetric Difference in Swift
Hey guys Leo here, Today we will start a series in this blog called: Algorithms, the Final Frontier. We’ll follow the interview prep series from the free code camp. The first challenge: Challenge Here The problem: Given two sets (for example set A = {1, 2, 3} and set B = {2, 3, 4}), the mathematical […]
How to initialize a 2D array full of zeros in swift?
Just use the array initializer (repeating: , count: ) as follows: var rows = 3 var column = 5 var arrayOfArrayInitialization = [[Int]](repeating: [Int](repeating: 0, count: column), count: rows) That’s all my people, I hope you liked reading this article as much as I enjoyed writing it. If you want to support this blog you can […]
