Problem types

Nina and Emilija are playing a game on a piece of paper. Initially, the paper is empty. In one move a player appends a letter to the end of the word that is currently written on the paper. They alternate turns, and Nina plays first.

Players must choose the letters in such a way that the following condition is met: the word that is written after the player's move must be a prefix of some word in that players favourite song. If the player can't make a move, she loses.

If both players play optimally, determine who wins.
