Given three integers A, B and C in [-263 , 263 ), you are supposed to tell whether A+B > C. 输入描述: The first line of the input gives the positive number of test cases, T (<=1000). Then T test cases follow, each consists of a single line containing three integers A, B and C, separated by single spaces. 输出描述: For each test case, output in one line "Case #X: true" if A+B>C, or "Case #X: false" otherwise, where X is the case number (starting from 1). 输入例子: 3 1 2 3 2 3 4 9223372036854775807 -9223372036854775808 0 输出例子: Case #1: false Case #2: true Case #3: false
