Binary Search is an algorithm that can find the index of an element in a sorted array data structure. You've likely used Binary Search it in everyday life without even realizing it.

If you're a CS student/beginner learning data structures & algos for the first time, I cannot recommend "A common-sense guide to data structures & algorithms" enough. It's a textbook that is focused on explaining the base concepts in plain English to a beginner. It goes in-depth without overwhelming you. Provides exercises, examples, & diagrams. Book saved my life freshman year of CS.

The code shown actually have a bug. When it was written back in the day it was not a problem. Now of your search array has billion elements the sum of integers may overflow and become negative. The new proper way to avoid going out of bounds of the integer to calculate mid point is int mid = low + ((high - low) / 2); This was a bug in Java for 9 years

Algorithm holds a massive part in today's technical world. Apart from dev tools like react, redux, and all including devops, algorithm is something we all get to ask even in interview. I appreciate the work you have done yet and doing continuously to get us know what that technology actually means and when should we have it in use. Other data structures and algorithms are welcome from my side. We all need it.
