Integer square root Newton

CodingAlgorithms & data structuresMid–Senior~20 min

Compute the integer square root of a non-negative integer x WITHOUT using any floating point (no math.sqrt, no **0.5): return the largest integer r such that r*r <= x. Use Newton's method (integer iteration). Constraints: 0 <= x <= 10^18. Example: isqrt(8) = 2, isqrt(16) = 4.

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
