Input
In the first line there is an integer T(T<=50), indicates the number of test cases.

In each case, the first line contains three integers N(1<=N<=50), X,Y(1<=X,Y<=200). Then there are N lines, each line contain two integers ai, bi (1<=ai, bi <=1000).

Output
For each test case, output “Case d: “ at first line where d is the case number counted from one, then output the shortest time to finish all the tasks.
