My issue
I am not able to get the direction to get to this question. Please help me and give me some direction.
As I am little confused that the length can be 10^18 but till that value long long cannot reach and I am unable to imagine using string here
My code
#include <iostream>
using namespace std;
int main() {
// your code goes here
return 0;
}
