合并 3 个列表（或更多）
我有 2 个字符串列表/数组
货币列表：
String [] 货币 = {EUR、USD、CAD 等}；时间段列表：
字符串 [] 周期 = {"T","O","SN","1M","1Y","1W","2M","3M","4M","5M ","6M","7M","8M","9M","10M","11M", ...};后缀列表：
字符串列表后缀 = {"D"、"FSR"、"ND"等}；
我想合并它们列表。我需要定义一个映射，因为我不想将所有合并到所有（更像是一些到一些）。
例如：
EUR 可以与句点中的“1M”和“2M”组合，以及与“D”和 后缀中的“FSR”。
美元可以与“1M”、“3M”和“4M”组合 句点，并带有后缀“ND”。
您建议我如何进行此映射？
I have 2 lists/arrays of strings
a list of currencies:
String [] currencies = {EUR, USD, CAD, etc};a list of time periods:
String [] periods = {"T","O","SN", "1M","1Y","1W", "2M","3M","4M","5M","6M","7M","8M","9M","10M","11M", ...};a list of suffixes:
String list suffixes = {"D", "FSR", "ND", etc};
I want to merge them lists. I need to define a mapping because I don't want to merge all to all (more like some to some).
For example:
EUR can be combined with "1M" and "2M" from periods, and with "D" and
"FSR" from suffixes.USD can be combined with "1M", "3M" and "4M" from
periods, and with "ND" from suffixes.
How would you suggest I do this mapping?

我会使用支持冲突的字典来做到这一点。这就是它们的目的。
I would do it using a dictionary that supports collisions. That is what they are built for.
