Same question i am going to ask because by simple logic the answer of test case
5 0.438588
5 0.515693 must be 11.400428Ă—2+9.695699=32.504271 but they saying answer is 31.8022945983
Kindly answer the question!
For test case 2 , it is giving 3.9999999996 by manual calculations , but it surely involves some maths to get exact answer .
Yes there is something more in this problem perhaps which we are missing out. Things will be clear after editorials are out. Till then check others submissions.
I think they will not provide editorials like previous contest
May be. Same question is explained here already , have a look.
