A string may use more than one type of delimiter to bracket information into "blocks." For example, A string may use braces {}, parentheses (), and brackets [] as delimiters. A string is properly delimited if each right delimiter is matched with a preceding left delimiter of the same type in such a way that either the resulting blocks of information are disjoint or one of them is completely nested within the other. Required:

Write a program that uses a single stack to check whether a string containing braces, parentheses, and brackets is properly delimited. Then, write another program that uses a single queue to check whether a string containing braces, parentheses, and brackets is properly delimited.
