For a while now, FatalEagle has been thinking about fast multiplication. He found the problem on SPOJ, MUL, and solved it without too much trouble. Then he found VFMUL on the same site, but the same code for MUL didn't pass as the SPOJ servers were really slow. Frustrated and desperate to show off demonstrate his fast multiplication code, FatalEagle has created a problem that really tests the accuracy and speed of your fast multiplication code.

    Hmmm. Is it possible for you to allow Lua on this question? Or is it not possible?
