the 1st test is like the sample
cout << "2.6346295\n;
cout << "4 4 2 1 3"    passed 1st test!

My program (on my PC) gives the right aswer on this test too, but Judge gives me WA1 !!!!
Please help)))

  ... there was main algorithm code, I didn't paste it here, so I want admins not to delete all this code.....
