Sqrt(x)

Explore how to compute the square root of a non-negative integer rounded down, by applying modified binary search. This lesson guides you through understanding constraints and implementing an efficient solution without relying on built-in exponentiation.

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.

Constraints:

  • ...
