题目描述:

I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B.

A,B must be positive.

输入描述:

The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines follow, each line consists of two positive integers, A and B. Notice that the integers are very large, that means you should not process them by using 32-bit integer. You may assume the length of each integer will not exceed 1000.

输出描述:

For each test case, you should output two lines. The first line is "Case #:", # means the number of the test case. The second line is the an equation "A + B = Sum", Sum means the result of A + B. Note there are some spaces int the equation.

样例输出:

Case 1:
1 + 2 = 3
Case 2:
112233445566778899 + 998877665544332211 = 1111111111111111110

python AC：

n = int(input())
for i in range(1, n + 1):  # 默认从0开始，后面那个数为不包括的数
    a, b = map(int, input().split())  # 实现两个值在同一行输入
    print("Case %d:" % i)
    print("%d + %d = %d" % (a, b, a + b))
    i += 1
