我有一個陣列
line_one = ["flinders street", "richmond", "east richmond", "burnley", "hawthorn", "glenferrie"]
user_input1 = "flinders street"
user_input2 = "glenferrie"
我如何計算兩個字串之間的距離？預期產出 5。

首先想到的是：
line_one = ["flinders street", "richmond", "east richmond", "burnley", "hawthorn", "glenferrie"]
user_input1 = "flinders street"
user_input2 = "glenferrie"
(line_one.find_index(user_input1) - line_one.find_index(user_input2)).abs
#=> 5

line_one = ["flinders street", "richmond", "east richmond", "burnley", "hawthorn", "glenferrie"]
代碼
p (line_one.index("flinders street")...line_one.index("glenferrie")).count
輸出
5
