Coding Interview Patterns — III — Fast and Slow Pointers is a technique used to solve programming problems relating to Linked List traversal, including, but not limited to, the following. LinkedList Cycle Middle of the LinkedList Palindrome LinkedList Preconditions These preconditions help identify that a problem may be solved using the Fast and Slow Pointers method. We…

Join me on my journey from drawing for fun, to Excel, over Python to a, probably working and good balanced card game But why? I own a Remarkable2 and from time to time I’m drawing random stuff on it, just for fun and recreation. I’m not a good painter, it’s not impressive…

The tmpnam() C function from stdio.h throws a strange, vague warning about the dangers of using it. main.c:(.text.startup+0x7): warning: the use of `tmpnam` is dangerous, better use `mkstemp` This warning is displayed on both Clang and GCC compilers with C standard versions ranging from c89 to c2x without debugging enabled, so it’s clearly an important warning. The file name as the return value is defined, but most…

In this coding guide, you’ll learn how to solve a seemingly difficult coding problem using the functional programming paradigm. I hope to demonstrate the relevance of this paradigm in 2023 and why it’s still important for new learners to hone in their functional programming skills. I’ll demonstrate which part of…

I believe that the most ignored topic in school is the algorithm complexity. Even professional developers or senior software engineers, we all might have a hard time understanding it thoroughly. Doing my own research, I’d like to recap what I found on the algorithm complexity, and Big O specifically. …

In Swift and Kotlin! — Many of us searching for jobs are concerned about technical interviews. We go straight to LeetCode and Hackerrank to solve as many problems as possible. This process results in becoming overwhelmed by the quantity and diversity of algorithms and data structures we need to memorize for specific problems. However, this…
