Binary vs. Linear Search and Ruby’s .find Method

I’m currently learning the Ruby programming language, and I was curious what kind of search is used in Ruby’s .find method for arrays. After a bit of searching around the docs, then figured why not find out for myself. I was interested to see what method of searching .find uses, and whether it was the fastest method to search through arrays or not.

To find this out, I wrote Ruby methods for linear search and binary search, implemented them, and tested their benchmarks with different sized arrays.

Here is how I implemented linear search:

Here is how I implemented binary…
