The stack
Suppose a arithmetic expressions can contain three kind of parentheses: garden \ (\ and\ ) \ , brackets, brackets \ [\ and\ ] \ , curly braces \ {\ and\ } \ , and the three brackets can be used according to the sequence of arbitrary nested. Write discriminant given expression in parentheses is properly matched the algorithm (known expression has been deposited in the data elements for the character sequence in the table). Requirements: order stack storage To realize the basic operations of stack order Call the basic operation is completed.
