Hi Experts of CF .

I am in a Fix. Hope someone of You can help me out . Here is my Problem :

Sometimes we can see there are several Problems whose Input Data co-ordinated with a Test Case & Several Tests under it. But It does not mention How many Data we have to take as input for a several Test Case . It just mentioned there that There would be a Blank line between Two Consecutive Test Cases . Even if There will be a Blank line between The input Number of Test Case & the First Test Case .As well as there will be a Blank Line between the Last & Second Last Case .But there is No Terminating Empty line after the Last test Case . For Example
