\n" ); document.write( "\n" ); document.write( "        As I read the solution in the post by @mananth, it makes me laugh.\r
\n" ); document.write( "\n" ); document.write( "        The runners are confused with trains, and the input numbers are confused with other, irrelevant numbers.\r
\n" ); document.write( "\n" ); document.write( "        The solution and the answer in the post by @mananth both are incorrect.\r
\n" ); document.write( "\n" ); document.write( "        So,  I came to bring a correct normal solution.\r
