Balanced delimiters
Balanced delimiters
EasyYour task
- Return true when every opening delimiter has a matching closing delimiter of the same kind, in the correct nesting order.
- Otherwise return false.
- Supported pairs are (), [] and {}.
Required API
- BalancedDelimiters
func BalancedDelimiters(text string) bool
Behavior
- Empty text is balanced.
- Adjacent balanced groups are valid, but crossed pairs such as ([)] are not.
Constraints
- The input is valid: text has 0–1,000 characters and contains only these six ASCII delimiter characters.
- Other characters are outside the input contract.
- Separate calls must not share state.
- Aim for O(n) time and O(n) extra space using only the standard library.
- Explain what an unmatched opening delimiter means on the stack.
Notes and example notation
Examples use {"text": "..."}.
