nice solution!

Isn't "Every digit is the same number" a sub set of "The digits are a palindrome"?

This makes checking for the first set superfluous. ;-)

Great kata to exercise with.

Great kata.

Stumped me for a few days. learned how to dynamically generate deep objects, so useful. thank you.

Great soln!!

Thanks for this solution!

like me

Santa Claus must still be waiting for this code to run

I assume that I can transfer the characters correctly from the browser to VS, i.e. converting from UTF8 to Unicode. `

"ẞtß".ToLower() gives hex:"DF-00-74-00-DF-00", therefore "t" is the single non-repeating char.

I make the same steps with "σtς" which gives: hex	"C3-03-74-00-C2-03".
From this result I would conclude that "σ" is the first non-repeating character. What is my mistake?

VS displays your 3rd string with an obviously different character than the browser.

Yes, Thanks !

Your function should return the first non-repeated char of the string, so, if the string has only 1 char, it should return that one. It's not repeated, is it? At least I think that's the way of understanding it.
