曾经做过一个类似的，也是对双引号进行修改。

这题要使用整行读人，我习惯使用gets()函数，当然也有其他的函数get(cin,string s)、cin.getline(charArray, max_length,'\n')。但有时做字符串题时会发生与换行符有关的错误，不能理解！

Sample Input

"To be or not to be," quoth the Bard, "thatis the question".The programming contestant replied: "I must disagree.To `C' or not to `C', that is The Question!"

Sample Output

``To be or not to be,'' quoth the Bard, ``thatis the question''.The programming contestant replied: ``I must disagree.To `C' or not to `C', that is The Question!''
