Last summer, one of three friends: Alen, Daniyar, and Nurdaulet married. Each of them chose a person $X$ (possibly himself) and either said that the person $X$ is married or that the person $X$ is not married. After hearing their statements and knowing that exactly one of them lied, Almas was able to conclude who actually married. For how many ordered triples of statements could this happen?
