When khann registered his codeforces account, he regrettably found that khann had already been registered, and he had to change his name to khannn
One day, khann suddenly wanted to create a alternate account
He decided to give his first alternate account the name khannnn
the second alternate account is khannnnn
the third alternate account is khannnnnn
And so on .......
Today khann just finished writing coding, and his pig brain overload, he gave you a codeforces account, can you tell pig brain overload khann the number of his alternate account?
A string, as khann's codeforces account
(the size of the string is less than 1000)
An integer , tells khann the number of the alternate account
khannnn
