Integer to Roman numeral
Convert an integer num (1 <= num <= 3999) to its Roman numeral string. Roman numerals use I=1, V=5, X=10, L=50, C=100, D=500, M=1000, with subtractive pairs IV=4, IX=9, XL=40, XC=90, CD=400, CM=900. For example 1994 = MCMXCIV.

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.
