In the statement, ' * ' operator is defined as

Vi = {m*S1  if i = 1, Vi-1 + Si-1  if i > 1}

But this definition doesn't match to the samples, so I think it should be

Vi = {m*S1  if i = 1, Vi-1 * Si  if i > 1}

I got both AC with this definition.

Yes. That's also how it was defined in the original contest problemset http://www2.mat.ua.pt/delfim/delfim/art ... UP2004.pdf.
