Software, Linux & Infrastructure
This blog is my workspace for building software, working with Linux systems, and developing technical infrastructure - with a focus on clear and structured solutions.Recently updated
The Bubble Sort Algorithm 🇦🇹
How bubble sort sorts a list by repeatedly swapping adjacent out-of-order elements, visualized as an animated bar chart with a C++ implementation.
The Heapsort Algorithm 🇦🇹
How heapsort turns a list into a binary heap and repeatedly extracts the maximum, visualized as an animated bar chart with a C++ implementation.
The Insertion Sort Algorithm 🇦🇹
How insertion sort grows a sorted prefix one element at a time by shifting larger values out of the way, visualized as an animated bar chart with a C++ implementation.
The Merge Sort Algorithm 🇦🇹
How merge sort repeatedly merges sorted runs into larger sorted runs until one remains, visualized as an animated bar chart with a C++ implementation.
The Quicksort Algorithm 🇦🇹
How quicksort partitions a list around a pivot and recurses on both halves, visualized as an animated bar chart with a C++ implementation.
The Selection Sort Algorithm 🇦🇹
How selection sort repeatedly finds the smallest remaining value and swaps it into place, visualized as an animated bar chart with a C++ implementation.
