EasyStackString
Valid Parentheses
Given a string made only of bracket characters, decide whether every opening bracket is closed by the matching type in the correct nested order.
Examples
Input: text = "{[()]}"
Output: true
Each pair closes in reverse order of opening.
Input: text = "([)]"
Output: false
The closing bracket types do not match the nesting order.
Constraints & goals
