Your little brother has just to write one, two, and three in English. He has written a lot of those words on a paper, and your task is to recognize them. Be aware that your little brother is only a child, so he may make some small mistakes: there might be at most one wrong letter for each word. The word length is always correct. It is guaranteed that each letter he wrote is in lower-case, and each word has a unique interpretation.

你的弟弟剛學會寫英文的一二三。他在一張紙上寫了很多這幾個字，而你的工作便是辨認它們。要注意的是你弟弟不過是個小孩子，因此他會犯些小錯誤：至多一個錯誤的字母。單字長度一定是正確的。他所寫的一定是小寫字母，每個單字只可能有一種合理解釋。
