Dice

Today I suddenly want to roll a die.

But I also want to write code.

So why not do both?

The first line contains the number of test cases $T$.

Each of the next $T$ lines holds one test case: the two numbers that came up when a die was rolled twice, separated by a space. Both numbers are integers from 1 to 6.

For each test case, print Case x: and then the sum of the two numbers rolled. The test case number $x$ starts at 1.
