C++, how do you sort chars in a queue??

bool is Sorted() const; This function checks if the queue is sorted in ascending or descending order. For example, if a queue contains A, C, and B, the function should return false. However, if the queue contains (A, B, B, F) or (F, B, B,A), it will return true. If the queue is empty or has only one element, the function should return true as well. tradicione de una semana en la cual lement de les
