I'll think about it tomorrow, I'm almost sleeping. But two quick thoughts: - check the idea of hash map in jdk 8+, how list/array in a bucket becomes a tree when threshold is reached - what if you implement compareTo to use combined name+age value, that way that ["tolstoy",32] > ["tolstoy",23] and build tree based on that comparator. Like using special type of hashes like in image searching
