Well we can try. \InputFile Each case will define two binary strings (\textbf{x} & \textbf{y}). You can assume that length of each string will not exceed \textbf{30}. The program will terminate with a \textbf{0} \textbf{0}. \OutputFile Output must be formatted like the following examples. You have to show the step by step procedure for the multiplication. Each result will be separated by an empty line.
