Multiple input problems The first line of a multiple input file is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.

The output format is the same as the input format, without the integer N (and without the blank line following it, of course), i.e.

The input should be like this: 
2 <-- The number of test cases
  <-- A blank line
3 <-- First data set
  <-- A blank line
3 <-- Second data set.

And the output should be like that: 
asdf <-- First output
     <-- A blank line
asdf <-- Second output


As an example, for problem number 100 a multiple input/output files could be as follows

Input 

3

1 10
100 200
201 210
900 1000

1 10
201 210
900 1000

100 200
201 210

Output 

1 10 20
100 200 125
201 210 89
900 1000 174

1 10 20
201 210 89
900 1000 174

100 200 125
201 210 89
