/*
1011. A+B and C (15)

Given three integers A, B and C in the interval [-2^31, 2^31], please determine whether A+B is greater than C.

Input format:
    Enter the first line to give a positive integer T (<=10), which is the number of test cases. Then T groups of test cases are given, each group occupies one line, and A, B and C are given in order.
    Integers are separated by spaces.
Output format:
    For each set of test cases, print "Case #X: true" in one line if A+B>C, otherwise output "Case #X: false", where X is the test case number (starting from 1).
Input sample:
4
1 2 3
2 3 4
2147483647 0 2147483646
0 -2147483648 -2147483647
Sample output:
    Case #1: false
    Case #2: true
    Case #3: true
    Case #4: false
