Use C++ to implement School Method for Integer Addition and Karatsuba Algorithm for Integer Multiplication

Your submission should contain exactly one file: main.cpp. You do not need to submit a design. Your program takes one line as input. The input line contains three integers separated by spaces. Let the three integers be I1, 12, and B. I1 and 12 are both nonnegative integers up to 100 digits long (there are no leading Os, except when the value itself is 0). B is I1 and 12's base (B is from 2 to 10).1 Your program should output the sum of I1 and 12, using the school method, then the product of I1 and 12, using the Karatsuba algorithm, and finally the ratio between I1 and I2 (rounded down). You are asked to come up with a way to perform this division. It's not covered in lectures. 12 will ot be 0. The results should still use base B. Please separate the results using one space. Sample input 1: 101 5 10 Sample output 1: 106 505 20 Sample input 2 10 111 2 Sample output 2: 1001 1110 0 Sample input 3: 111 102 Sample output 2: 1001 1110 11 If you are an undergraduate student, simply output 0 as the division result. For sample 3, instead of 1001 10 11, simply output 1001 1110 0
