Background For a computer, an image is collection of interpretable instructions that amount to a visual representation. Raster images are composed from using pixels, containing unique colours, whereas vector images keep track of points and equations that join them. In \(\LaTeX\) PGF/TikZ is used to generate vector graphics from algebraic descriptions. TikZ is mostly used to conveniently draw various scientific figures. ChatGPT is capable of generating computer code in majority of popular languages....

Big-O The purpose of this is not to provide yet another primer on the Big-O/$\Omega$/$\Theta$ notation but to share my enduring appreciation for working with R. I will introduce Big-O only briefly to provide context but I would refer all of those who are interested to the linked materials. What is Big-sth notation… When analysing functions, we may be interested in knowing how fast a function grows. For instance, for function \(T(n)=4n^2-2n+2\), after ignoring constants, we would say that \(T(n)\) grows at the order of \(n^2\)....

Problem Solving challenges on project Euler or HackerRank is a good past time. For folks working in the wider analaytical / data science field, places like project Euler provide an excellent opportunity to work with academic programming concepts that do not frequently appear in real-life. I was looking at common problem: You are given an unordered array consisting of consecutive integers [1, 2, 3, …, n] without any duplicates. You are allowed to swap any two elements....
