{"ops":[{"insert":"Read about doing multiplication using Karatsuba method\nWrite a C++ program which:\n\u2022 Prompts user to enter two large integer numbers (x, y).\n\u2022 Make a function called Karatsuba() which takes these two integers and returns the\nmultiplication result using Karatsuba algorithm.\no Your function should do parameter validation. Both numbers must be more\nthan 4 digits and less than 10 digits (don\u2019t use strings). If parameters are not\nvalid then the function should return 0;\no The entered numbers could be negative or positive. For example: 820778 and\n-58712979 where x is 6-digit positive number and y is 8-digit negative\nnumber.\n\n\u2022 You might need to make another helper function called getDigits() which will get an\ninteger as input and returns number of digits of that integer. getDigits() will help you\nfind the value of m and Bm.\n\u2022 Finally, display result in the main function\n"}]}
