How do you perform a binary search in a given array in Ruby

Ruby

🤖 Code Explanation

This is a method for searching an array for a given target value using a binary search. The method takes in an array and a target value as parameters. The low variable is set to the first index in the array, and the high variable is set to the last index in the array. Then, while low is less than or equal to high, the middle index is calculated by taking the average of low and high. Then, the element at the middle index is compared to the target value. If they are equal, the index of the target value is returned. If the element at the middle index is greater than the target value, then high is set to the middle index - 1. Otherwise, if the element at the middle index is less than the target value, then low is set to the middle index + 1. If the target value is not found in the array, then nil is returned.
