I am stuck on this problem JUSTAPAL12.

My idea is

  1. All the character whose occurrence is even should be in the final solution
  2. For all odd occurrence characters, characters with the maximum count should be there.

Am I wrong somewhere?

I don’t understand how your idea gives the solution. Please could you work through an example?
