问题 I'm trying to declare a function, string list -> string, that with the input for instance ["Chicago","city","USA"] should return "Chicago city USA" . What I did so far was this: fun gather ts = foldr op ^ "" ts; This seems to be somewhat along the lines, however the problem is, I would like to include the spaces between the words, as this function would return "ChigagocityUSA" . 回答1: Yes, the problem is that ^ is a function that for two strings "foo" and "bar" returns "foobar", although you
