Minimum insertions to make palindrome

CodingAlgorithms & data structuresMid–Senior~25 min

Given a string s, return the minimum number of characters you must insert anywhere to turn s into a palindrome. 1 <= len(s) <= 500, s contains lowercase letters only.

Implement
min_palindrome_insertions(s: str) → int
Examples
in["zzazz"]out0
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.
