Validate Brackets Function | Dataford Interview Questions

Write a function to validate a string of brackets.

Implement is_valid_brackets(s) to return True when every opening bracket has the correct closing bracket in the correct order. Support (), [], and {}. Return False for mismatches, incorrect nesting, or unmatched brackets. The input contains only bracket characters, and an empty string is valid.

Example: "{[()]}" returns True; "([)]" returns False.

Constraints

0 <= len(s) <= 10^4
s contains only the characters '(', ')', '[', ']', '{', and '}'
