Q: Compute square root with precision

This question evaluates a candidate's understanding of numerical methods for root finding, floating-point precision control, and algorithmic time complexity analysis when computing square roots without built-in functions.

Given a non-negative integer val and a non-negative integer precise, compute the square root of val without using any built-in square-root function. Return a result whose absolute error is at most 10^-precise. Also explain the time complexity of your approach.
