Thank you. I don't know why I always got wrong answer yesterday with this code.
But I got AC now. Thanks.

What is wrong with my problem? I got wrong answer.

My code:


#include<iostream>
#include<cstdlib>

using namespace std;

int main()
{

int num1,num2,count,add;


cin>>num1>>num2;
while(num1||num2)
{
count=0;
add=0;



while(num1||num2)
{
add=(num1%10+num2%10+add)/10;
if(add)
{
count ...
