BST Diameter

Earlier this morning I read a post “Binary Tree: The Diameter” by David Pynes. The post showed up on Medium but was initially written for Towards Data Science. After quickly reading the post I decided to spend time reading the article in my computer, thinking about it and writing a solution in Java. The original article used C++.

Binary Tree – Heap

I read an article or two from Medium every day. A few days ago I read “Binary Trees: The Heap” by David Pynes.

The logical thing would be to allow them to see a physician before patients that are less ill. Continue reading “Binary Tree – Heap”

Simple Problems in Python

The reason I agree is that I have been a believer in “If you can’t explain it simply, you don’t understand it well enough”. This quote is attributed to Albert Einstein.

Using Docker – Installation

If you follow me on Twitter (@john_canessa) you have noticed that in the past couple months or so I have been posting tweets regarding articles in Medium. The site is geared to creating posts which you could do using your own web site (e.g., www.johncanessa.com). The beauty is that many talented individuals in different fields are posting there. The site organizes them by categories and presents the articles indicating the estimated reading time. One of these days I will probably start posting there.
