Pangram Problem – Haskell [Problem Solved]
Background This problem comes courtesy of the great folks over at Exercism. I highly recommend jumping on their Haskell track to apply your knowledge of Haskell. The Problem Your task is to figure out if a sentence is a pangram. A pangram is a sentence using every letter of the alphabet at least once. It…

Recursion – Haskell
Recursion is a concept in programming where a function calls itself in order to solve a problem. Recursive functions are useful when a task can be broken down into similar subtasks, allowing the function to repeat its own logic until it reaches a stopping point (called the base case). In Haskell, a functional programming language…

Why do we always split a list into a head and a tail in Haskell?
In Haskell, lists are defined recursively as a head (the first element) and a tail (the remainder of the list). This structure allows for easy and efficient pattern matching, recursion, and functional operations on lists. Here’s why we often split lists into head and tail: 1. Simplicity of Recursive Definitions Example: Sum of a List…

Space Age Problem – Haskell [Problem Solved]
Background This problem comes courtesy of the great folks over at Exercism. I highly recommend jumping on their Haskell track to apply your knowledge of Haskell. The Problem Given an age in seconds, calculate how old someone would be on: So if you were told someone were 1,000,000,000 seconds old, you should be able to…

Understanding the Type System in Haskell
Haskell is known for its strong and expressive type system, which serves as both a powerful tool for error-checking and a guide to writing clear, maintainable code. Haskell’s type system helps you define precisely what kinds of data your functions expect, process, and return, ensuring that code behaves as intended while eliminating many types of…

Tuples – Haskell
In Haskell, tuples are a powerful and versatile way to store and work with multiple values. Unlike lists, which hold elements of the same type, tuples allow you to combine values of different types within a single, fixed-size structure. This makes tuples especially useful for grouping related but distinct pieces of data, like coordinates, database…

Guards – Haskell
Haskell provides several features that allow for elegant and expressive code. One such feature is guards, which give you a powerful way to express complex conditional logic in a clean and readable manner. Guards allow you to write functions that branch based on different conditions, offering a clearer alternative to multiple if-else statements. In this…

The Difference Between Strict and Lazy Functions in Haskell
Haskell is known for its lazy evaluation model, a distinctive feature that sets it apart from most other programming languages. In Haskell, computations are delayed until their results are actually needed. This concept of laziness can be contrasted with strict evaluation, which is the default in many other languages where expressions are evaluated immediately when…

Imperative Programming Languages
Imperative programming languages are those in which the programmer provides step-by-step instructions on how the computer should perform tasks. These languages are based on commands that change the program’s state through assignments, loops, conditionals, and explicit sequences of actions. They focus on how to achieve a specific outcome, as opposed to what the outcome should…

A Deep Dive on Understanding Hash Functions in Cryptocurrency
Cryptocurrencies like Bitcoin, Ethereum, and Cardano are built on cryptographic foundations that ensure security, transparency, and decentralized control. One of the most critical cryptographic tools underpinning these systems is the hash function. It’s an indispensable component in blockchain technology, contributing to everything from transaction validation to consensus mechanisms. In this deep dive, we’ll explore exactly…
