Introduction

Binary Search — The Algorithm You Underestimate Every Single Day

Four lines of code, and Java shipped them broken in the standard library for eight years. The idea was never the hard part.

Recursion Isn’t the Problem. The Stack Is.

Recursive code can be perfectly correct and still crash. The reason isn’t recursion. It’s where the unfinished work gets stored.
