In the game of Sports, the object is have more points than the other team after a certain amount of time has elapsed. Scores are denoted by two hyphen-separated integers. For example, scores may include 3-2, 4-1, or 10-0. The first number is how many points you've scored, and the second is the number of points scored by the opposing team. You're very good at Sports, and consequently you always win. However, you don't always achieve victory the same way every time.

The two most extreme kinds of victory are called stress-free and stressful. In a stress-free victory, you score the first point and from then on you always have more points than your opponent. In a stressful victory, you never have more points than your opponent until after their score is equal to their final score.

Given the final score of a game of Sports, how many ways could you arrange the order in which the points are scored such that you secure a stress-free or stressful win?

Input

Input begins with an integer T, the number of games you'll play. For each game, there is one line containing the final score of the game in the format described above.

Output

For the ith game, print a line containing "Case #i: " followed by two space-separated integers, the number of ways you can achieve a stress-free or stressful win, respectively. Since these numbers may be very large, output them modulo 1,000,000,007.

Constraints

1 ≤ T ≤ 100

Since you always win, the first number in any final score will always be larger than the second. Both scores will be non-negative integers not exceeding 2000.
