ifelse

#4263

Studiind instrucțiunea if, Alinutza a aflat că ramura else se asociază celui mai apropiat if neasociat încă. Aprofundând studiul, a extras din fiecare program scris cuvintele if și else. Din neatenție a transcris greșit, pierzând asocierea corectă if else. Ajutați-o voi să aibă scrierea corectă, folosind un număr minim de modificări. O modificare înseamnă să înlocuim un cuvânt if cu else sau un cuvânt else cu if.
