問題：

????在終端輸入多行信息，找出包含“ould”的行，并打印改行。

????如：

Au,love could you and I with fate conspire

To grasp this sorry scheme of things entire,

Would not we shatter it to bitd – and then.

在終端輸出上述的文字，輸出

Au,love could you and I with fate conspire

Au,love could you and I with fate conspire

To grasp this sorry scheme of things entire,

Would not we shatter it to bitd – and then.

Would not we shatter it to bitd – and then.
