示例1: main
int main() {
std::string text;
getline(std::cin, text); // get the input string
std::stack <Bracket> opening_brackets_stack;
for (int position = 0; position < text.length(); ++position) {
char next = text[position];
if (next == '(' || next == '[' || next == '{') { // store the left bracket in the stack
Bracket parenStart(next, position);
opening_brackets_stack.push(parenStart);
}
else if (next == ')' || next == ']' || next == '}') { // if right bracket is detected
if (opening_brackets_stack.empty()) // if the stack is empty, which means no left bracket is stored
{
std::cout << (position + 1) << std::endl; // output the position of this right bracket, break loop
break;
}
else
{
Bracket parenStartOut = opening_brackets_stack.top(); // get the latest left bracket,
//remove it from stack
opening_brackets_stack.pop();
if(!parenStartOut.Matchc(next)) // check if the latest left bracket is matched with
// the current right bracket
{
std::cout << (position + 1) << std::endl; // if not, output the position of this right bracket, break loop
break;
}
}
}
if (position == text.length() - 1) // if reach the end of the string
{
if (!opening_brackets_stack.empty()) // if the stack is not empty, output the position of
//left bracket at the end of the stack (the first unmatched one)

}
else // if stack has no left bracket, which means all the brackets have been matched
{
