去哪兒筆試解決方案

有兩個文件context.txt和words.conf,請嘗試將他們合併成爲一段文字，並打印出來。 這兩個文件內容如下： context.txt 
“並不是每個人都需要$(qunar)自己的糧食，$(flight.1)每個人都需要做自己穿的$(flight.2)，我們說着別人發明的$(hotel)，使用別人發明的數學......我們一直在$(tuan)別人的成果。使用人類的已有經驗和知識$(travel.1)來進行，是一件$(travel.2)的事情”   
word.conf 

flight=也不是：衣服 

qunar=種植 

hotel=語言 

tuan=使用 

travel=發明創造：很了不起

解決方案：
