我刚刚在http://repl.it/2Om/6找到CodeGolf个答案：
puts"The eight#{e="een-hundreds were a time for "}rum.
The ninet#{e}fun.
The two-thousands are a time to run
a civilized classroom.
"*(?X-??)

我很好奇，它是如何运作的？我以前从未见过(?X-??)。这里发生了什么？
答案 0 :(得分：4)
？Char给出Char的ASCII码。
?X = "X".ord = 88
?? = "?".ord = 63
?X - ?? = 88-63 = 25
There is your integer: 25
Then "a"*25 = "aaaaaaaaaaaaaaaaaaaaaaaaa"
