如何从ruby中哈希数组中的范围中找到最小值？(How to find the minimum value from the ranges in array of hashes in ruby?)

如何从ruby中哈希数组中的范围中找到最小值？(How to find the minimum value from the ranges in array of hashes in ruby?)

我有下面的哈希数组

z = {"RANGE"=>[{"10-50"=>"5"}, {"50-100"=>"15"}, {"100-150"=>"25"}]}

如何将输出设为10

I have the below array of hashes

z = {"RANGE"=>[{"10-50"=>"5"}, {"50-100"=>"15"}, {"100-150"=>"25"}]}

How can I get output as 10

最满意答案

您可以尝试以下方法：

z["RANGE"].map(&:keys).flatten.map(&:to_i).min #=> 10

演示

You can try the following:

z["RANGE"].map(&:keys).flatten.map(&:to_i).min #=> 10
