Recall the stack-based algorithm (where an opening brace or a parenthesis is pushed into the stack, and on encountering closing braces or parentheses, a pop is performed on the stack) for determining whether a sequence of parentheses is well formed or not (balanced). If the given string is: Then what is the maximum number of brackets that would appear in the stack at any instant? A bracket in this context can be any one of the following four types: '(', '{', '}' and ')'. The sequence can be either well formed or ill formed. a :2 b:3 C: 4 d:5
