ruby - 在 Ruby 中将字符串的部分与数组的元素匹配

Question

我有一个字符串和一个数组，我试图遍历数组以查看它的任何元素是否与字符串的一部分匹配。

string = "HOPJYJKCONNECTICUTQZIDAHOKR"

states_array = ["TEXAS", "ALASKA", "IDAHO", "FLORIDA", "MONTANA", "OHIO", "NEWMEXICO", "CONNECTICUT", "COLORADO"]

如何遍历 states_array 以便找到字符串中的所有匹配项？我想将所有匹配的状态输出为一个数组，所以最终结果可能如下所示:

#=> ["CONNECTICUT", "IDAHO"]

Answer 1

string = "HOPJYJKCONNECTICUTQZIDAHOKR"
states = ["TEXAS", "ALASKA", "IDAHO", "FLORIDA", "MONTANA", "OHIO", "NEWMEXICO", "CONNECTICUT", "COLORADO"]

states.select { |s| string[s] }
# => ["IDAHO", "CONNECTICUT"]
