• $S_i$ $(1 \leq i \leq N)$ are strings consisting of lowercase English letters.
• The length of $S_i$ $(1 \leq i \leq N)$ is between $1$ and $10$ (inclusive).

beet and vet are written on two sheets each, while beat, bed, and bet are written on one vote each. Thus, we should print the strings beet and vet.
