Question
Given a string query, classify it as a valid "IPv4" address, a valid "IPv6" address, or "Neither". An IPv4 address is four dot-separated decimal groups, each 0-255 with no leading zeros (so "192.168.01.1" is invalid). An IPv6 address is eight colon-separated groups, each 1 to 4 hexadecimal digits (case-insensitive); do not support :: compression. Return one of the exact strings "IPv4", "IPv6", or "Neither".
validate_ip(query: str) → str["172.16.254.1"]out"IPv4"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.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
