Connections is a word categorization game. You are given 16 Chinese words, and your task is to divide them into 4 groups, each containing 4 words, with each word appearing exactly once. The words within each group must share a strong association, and this association must be stronger than just being "two-character verbs."
An example is provided below:
Word List:
| :---: | :---: | :---: | :---: | | A.一半 | B.一角 | C.嘴角 | D.干冰 | | E.室女 | F.抵抗 | G.未知 | H.军车 | | I.吕方 | J.出山 | K.生辰 | L.乘法 | | M.道头 | N.交叉 | O.楼房 | P.关闭 |
In this example, the four groups are:
- The first character is two of the second character: 一半, 出山, 吕方, 道头
- Adding a "日" (sun) character to the first character forms a new word: 生辰, 干冰, 军车, 一角
- Each character contains one of the Twenty-Eight Mansions: 室女, 嘴角, 楼房, 抵抗
- Symbols for X: 乘法, 交叉, 未知, 关闭
Therefore, you can output:
AJIM KDHB ECOF LNGP
as the answer.
Now that you have learned the basic rules of Connections, it is time to try the challenge!
