Since Google APAC is one of the few contests where there is no official editorial/analysis available, I decided to write a short editorial for Round A of Google APAC 2017. You can read the problem statements from this link.

Problem A

You need to find the number of distinct uppercase English alphabets in each of the given strings. Out of all those strings who have the maximum number of distinct alphabets, simply output the smallest one in the lexicographic order. Be careful while taking input for the large test data as the strings might contain spaces too.[](http://pastebin.com/7iV1uEEg) Code
