\n" ); document.write( "\n" ); document.write( "It is a  Math  Circle  level problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So,  I assume that the person who came with such problem,  has an adequate level in  Math\r

\n" ); document.write( "\n" ); document.write( "For such a person,  this  TEMPLATE  and my reference is enough and even more than enough.\r
