[Hackerrank Challenges - Sherlock and Squares ] (https://www.hackerrank.com/challenges/sherlock-and-squares/problem)

CM: This challenge requires strategy, not brute force.

I look at the square root of the minimum and the maximum in the supplied range. If the minimum is itself a square number, I add one to the counter. Then I count the integers in the range.

This is a good challenge for recruitment purposes.
