Honey barrels

Businessman Vasiliy started a new business – shipping honey in barrels. It is important for his partners to know how many barrels of honey are shipped each day.

Vasiliy's mobile phone only supports translit, so he sends messages in the format "$n$ bochek". For example, "$3$ bochki" or "$1$ bochka".

Write a program that selects the correct word (from "bochka", "bochek", or "bochki") depending on $n$.
