okay so as you can see i am doing project euler 13 and i alreay converted each digit from string to integer. as you can also see i am printing out my linked list as well and i was able to store the numbers in reverse. i need help using only one other linked list to print out the total summation of all the numbers and i need it to also only print out the first 10 digits of the total summation.

int main() ifstream inFile; string line; NodePtr head = nullptr; unsigned int number; infile.open('nuns.txt); if(infile.fail() cerr "Error unable to open filel" = && number 9) add_head_1(head, number): infile.close(); cout
