It's Christmas time again. And our mhBigCow falls in love with a girl again.As we all know, mhBigCow is a little shy to express his love to that girl. As we all know again,mhBigCow is quite a excellent coder,so he chooses to encode his message into binary bits. ASCII includes definitions for 128 characters: 33 are non-printing control characters (now mostly obsolete) that affect how text and space is processed; 94 are printable characters, and the space is considered an invisible graphic. The most commonly used character encoding on the World Wide Web was US-ASCII until 2008, when it was surpassed by UTF-8.<br>Simplified,mhBigCow chooses 8-bits to represent a char.He codes all night long and give the paper with the message to the girl. But the problem comes: The girl knows nothing about ASCII..So she asks you for help.<br>
As a good friend of mhBigCow,can you help her ?

There are several test cases.
Each test case with only one line of binary string. Note the length of the string will not exceed 1000.

##输出格式##
For each test case, you should output one line containing the result string you get.
Note that if the length of input string is not a multiple of 8,just output "oops! what is this".
