Multiply strings
Given two non-negative integers num1 and num2 represented as strings (no leading zeros except '0' itself, 1 <= len <= 200), return the product as a string. You must not convert the inputs to a language big-integer type or use built-in arbitrary-precision multiplication; implement the schoolbook algorithm.

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.
