+# Loteria
+
+Flavinho sabe que a chance de ganhar na loteria é bem pequena. Ele gosta muito
+de estudar probabilidade! Mas, justamente por entender de probabilidades,
+Flavinho segue o ditado, “quem não arrisca, não petisca!”, e faz um jogo toda
+semana.
+
+Na loteria preferida dele, o jogador aposta seis números entre 1 e 99. No
+sorteio, também são escolhidos seis números ganhadores entre 1 e 99. Quem acerta
+3, 4, 5 ou 6 números ganha como prêmio, respectivamente, um “terno”, uma
+“quadra”, uma “quina” ou uma “sena”.
+
+Nesta tarefa, você deve escrever um programa que diga qual foi o prêmio que
+Flavinho ganhou, dados os seis números que ele apostou e os seis números que
+foram sorteados.
+
+## Entrada
+
+A entrada consiste de duas linhas apenas. Na primeira linha são dados seis
+números inteiros distintos entre 1 e 99, representando a aposta do Flavinho. A
+segunda linha contém os seis números inteiros distintos sorteados.
+
+## Saída
+
+Seu programa deve imprimir uma linha contendo uma palavra: “terno”, “quadra”,
+“quina” ou “sena”; caso Flavinho tenha acertado, respectivamente, 3, 4, 5, ou 6
+números. Caso ele tenha acertado menos do que 3 números, imprima a palavra
+“azar”.
