Problem Statement

Hamsters, possessing advanced intelligence, have been remarkably active in international society.
It is only a matter of time before the hamster language replaces English as the next-generation lingua franca.

Being a person of foresight, you are starting by learning the numerals of the hamster language.
The numerals of the hamster language have the following characteristics.
・A numeral is a string consisting only of lowercase letters.
・It represents an integer greater than or equal to 0.
・It is a binary notation in which "hamu" represents 1 and "ham" represents 0.
・Just as leading zeros are not allowed in Arabic numerals, leading hams are not allowed in the hamster language.

For example,
・"hamuhamhamu" is 101 in binary, so it is a hamster language numeral representing 5 in decimal.
・"hamhamuhamu" is 011 in binary, but leading hams are not allowed, so it is not a hamster language numeral.
・"hamstring" means the muscles at the back of the thigh in English, but it is not a hamster language numeral.

Given a hamster language numeral, output the value multiplied by 2 as a hamster language numeral.
