When considering the push() and pop() operations for a stack, how could a compiler program use a stack to implement delimiter matching. For example, matching delimiter strings could be: “{â€, “}â€, “(â€, “)â€, and “/*â€, and “*/â€. Solution private static final char[] opening = new char[]{\'(\', \'[\', \'{\'}; private static final char[] closing = new char[]{\')\', \']\', \'}\'}; and stack integer can be denoted so that if the value is -1 then there is an error else matched. How stack is used in delimiter matching: 6) if the stack is not empty finally at the end then report missing right delimiter error .
