Given positive integer \textbf{N} (\textbf{1} ≤ \textbf{N} ≤ \textbf{100}), which determines a person's age. Bring out a number and a corresponding prefix in the Ukrainian language: "\textbf{рік}", "\textbf{роки}", "\textbf{років}". For example, \textbf{1 рік}, \textbf{12 років}, \textbf{94 роки}. \InputFile Single number - a person's age. \OutputFile Derive age with proper attachment. \textbf{Attention!!!} Attention! For correct display and test solutions installed system requirements: message output translit, that is, instead of "\textbf{рік}" must withdraw "\textbf{rik}", instead of the "\textbf{роки}" - "\textbf{roki}", and instead of "\textbf{років}" - "\textbf{rokiv}".
