I am a lonely Python/C++ coder with a background in financial markets and an interest in modern art. I am an application-driven guy, not a computer scientist. Sure I have many gaps in my knowledge, but I strive to do my best to fill them. I keep learning new things, listening to smart guys, correcting my mistakes, and pushing myself to the limits. I enjoy it.
I will use this website both as a blog and as a hub to some of my projects. It is written from scratch in Python's Flask, my favourite web-framework.
One thing I happen to see many times in interviews, coding challenges, or tutorials on recursion is the Fibonacci sequence. It is a coding evergreen. Fibo is a famous series of numbers where each element is the sum of the two previous. The...
You have a collection of items and you need to keep the N highest or lowest of them. Instead of writing your own algorithm, use build-in heapq module.
This module has two handy functions, nlargest(), and nsmallest().
This is...
C-style arrays might be tricky. Even such a trivial task like appending an element might surprise you. It actually surprised me a few times. I do not use raw array in day-to-day programming, I always prefer vector or std::array if I need a...

You want to do it as effectively as possible, no copying, no raw loops. Quite a typical use...
Humans use decimal numbers, computers use binary numbers. A common testing task is to write a function that converts a decimal number to a binary. There is no stl algorithm for that.
But why to stop here, why not to write a function...
