Solution Review: Integer Square Root
Explore how to implement an efficient integer square root function by applying the binary search algorithm. This lesson helps you understand how to optimize brute force solutions by narrowing down search ranges for a given integer k, ensuring you can find the largest integer whose square is less than or equal to k.

First of all, let’s repeat the problem statement.
You are required to write a function that takes a non-negative integer, k, and returns the largest integer whose square is less than or equal to the specified integer k.
Algorithm #
The naive approach to solve this problem is to start from 1 and check the square of every number up until k. Have a look at the ...
