以上是朋友圈中一奇葩貼:「2月14情人節了,我決定造福你們。第2個贊和第14個讚的,我介紹你倆認識…………咱三吃飯…你倆請…」。現給出此貼下點讚的朋友名單,請你找出那兩位要請客的倒黴蛋。c++
輸入格式:spa
輸入按照點讚的前後順序給出不知道多少個點讚的人名,每一個人名佔一行,爲不超過10個英文字母的非空單詞,以回車結束。一個英文句點「.」標誌輸入的結束,這個符號不算在點贊名單裏。code
輸出格式:blog
根據點贊狀況在一行中輸出結論:若存在第2我的A和第14我的B,則輸出「A and B are inviting you to dinner...」;若只有A沒有B,則輸出「A is the only one for you...」;若連A都沒有,則輸出「Momo... No one is for you ...」。ci
