28. 字串操作
輸入兩個英文句子A, B,以及兩個英文單字 X, Y，操作步驟如下:
1. 將兩個英文句子A, B串聯成句子 C （A和B兩個句子串聯時，中間用空白隔開），並輸出C
2. 將句子C中的單字X替換成Y變成句子D，並輸出D
（1）假如句子C中有個單字為Cards或是Card$，X=Card，此時並不符合替換條件
（2）無視單字大小寫差異
3. 輸出C和D的各自字串長度（不包含空白，但包含符號），中間以空白隔開
4. 將句子D中單字為Y的部分倒著輸出（假如句子D中有個單字為Cards，Y=Card，此
時並不符合倒著輸出條件）
5. N為單字X和單字Y的字數差異，N為大於0的整數（即X和Y字數不會相同）
6. 將句子C從第1個字開始，每隔N個輸出（輸出過程中，不得連續輸出2次空白）
