PAT——1011. A+B和C
给定区间[-231, 231]内的3个整数A、B和C,请判断A+B是否大于C。
输入格式:
输入第1行给出正整数T(<=10),是测试用例的个数。随后给出T组测试用例,每组占一行,顺序给出A、B和C。整数间以空格分隔。
输出格式:
对每组测试用例,在一行中输出“Case #X: true”如果A+B>C,否则输出“Case #X: false”,其中X是测试用例的编号(从1开始)。
输入样例:
4
1 2 3
2 3 4
2147483647 0 2147483646
0 -2147483648 -2147483647
输出样例:
Case #1: false
Case #2: true
Case #3: true
Case #4: false
