Implementing High-Precision Arithmetic with String Manipulation
Integer Addition Implementation
High-precision arithmetic handles numbers exceeding built-in type limits using string representations. For integer addition:
string integer_addition(string num1, string num2) {
string result;
int carry = 0;
int len1 = num1.length(), len2 = num2.length();
int max_len = max(len1, len2);
if ...
