Distinct Characters Subsequence | CodeChef

I m getting WA.I couldn’t find the error. Can soneone help??

I think you are approaching wrong. You have to calculate total number of distinct characters in the string which will be at max 26 in this case.

You’ve misunderstood the question. A subsequence may not neccassarily be contigous.
