附加说明:
- 为了使它更有趣，请用文字 只能通过使用 北美经典上的字母 带有三个字母的键盘电话 每个数字如此处定义. 这表示Z和Q排除在外.
- 对于数字"1"，请放置一个空格.

推荐答案
q， 52 39个字符
q, 52 39 chars
(cross/)(3 cut"--- ",.Q.A except"QZ")
q是从右向左求值的.
q is evaluated left of right.
.Q.A包含向量"ABC ... XYZ"
.Q.A contains the vector "ABC...XYZ"
except返回x，不包括y中的值
except returns x excluding values in y
将-"连接到修改后的char向量上
join "--- " to the modified char vector
切成3块
cross返回所有可能的组合，并应用于所有块
cross returns all possible combinations, and is applied across all chunks
q)(cross/)(3 cut"--- ",.Q.A except"QZ")[4 2 8 5 2 4 6]
"GATJAGM"
