If there is an array with the string
let str: String = ["Tokyo (10)", "Osaka (20)", "Hokkaido (30)"]
, I want to extract only the parts "10", "20", and "30".
Because the number of characters is not constant as shown above in the example,
The method of ◯ letter from the beginning cannot be used.
In my opinion,
The third character from the end, and the range of two characters from that point
I was wondering if it would be like that, but
I can't find anything good ...
I wonder if it is easy.

This is a postscript.
I want to use this string (10 or 20) for sorting.
I want to use the extracted string as it is, so I want to embed it in one sentence without putting it in a variable.
