I have a very simple problem for you again. Given two integers A and B, your job is to calculate the result of A - B.
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.
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 = ?”, ? means the result of A - B.Note there are some spaces int the equation. Output a blank line between two test cases.
3 9 8 12 8 123456789 987654321
Case 1: 9 - 8 = 1 Case 2: 12 - 8 = 4 Case 3: 123456789 - 987654321 = -864197532
Please run you code firstly. |
