 /**
- * The nested brackets problem is a problem that determines if a sequence of
- * brackets are properly nested. A sequence of brackets s is considered properly
- * nested if any of the following conditions are true: - s is empty - s has the
- * form (U) or [U] or {U} where U is a properly nested string - s has the form
- * VW where V and W are properly nested strings For example, the string
- * "()()[()]" is properly nested but "[(()]" is not. The function called
- * is_balanced takes as input a string S which is a sequence of brackets and
- * returns true if S is nested and false otherwise.
+ * BalancedBrackets.java
+ * Optimized valid parenthesis checker

+ * Supports: (), [], {}, <>
+ *
+ * Rules:
+ * - Returns true if brackets are properly nested and matched.
+ * - Returns false for any non-bracket character.
+ * - Empty string is balanced.
+ * - Null input throws IllegalArgumentException.
+ *
+ * Time complexity: O(n)
+ * Space complexity: O(n) in worst case (stack contains all opening brackets).
