Sqrt(x)
Explore how to implement an efficient algorithm to compute the integer square root of a non-negative number. Learn to apply modified binary search techniques to find the floor of the square root without using built-in exponent functions. This lesson helps you understand problem constraints and optimize your solution for coding interviews.

Statement
Given a non-negative integer x, compute and return the square root of x rounded down to the nearest integer. The result must also be non-negative.
Built-in exponent functions or operators (e.g., pow(x, 0.5) in C++ or x ** 0.5 in Python) are not permitted.
