Talk:Unique characters in each string

Input?

I suggest using an input that illustrates the problem more closely. As it stands, taking the intersection yields the correct output because there aren't any characters that

• repeat multiple times within a single string
• are present in all strings

I propose using ["1a3c52debeffd", "2b6178c97a938sf", "3ycxdb1fgxa2yz"], since f now meets the above criteria and an intersection no longer produces the correct output. --Chunes (talk) 07:15, 9 May 2021 (UTC)
