Consider strings constructed using only the following characters ‘(‘, ‘)’, ‘[’, and ‘]’. Character ‘(’ matches with only ‘)’ and ‘[’ matches with only ‘]’. A string comprising of these characters is complete if every character is followed by its matching character or a substring that is complete followed by its matching character. For example “()”, “[]”, “([])”, “[]([]())” are all examples of complete strings, while “([)]” and “[][(])” are examples of incomplete strings. Write program using character stack which accepts such strings as input and prints “Complete” or “Incomplete”.
