Check the sample very carefully.

I have tried all sample inputs in this thread and got correct answers.However the on-line judge is giving WA.I can't find any bug.Could someone please help me to track down the bug?
here is my code:

can any body give some critical input case?

@sazzadcsedu,
When your x is greater than 9, you set carry to 1. But if x<=9 the carry should be set to 0. You forgot that.
Good luck.

}
}

[Articuno]

Well there are a few lines you should recheck:
The format specifier for long data type is %ld , not %lld.
And you should also change this line:

Code: Select all

while(scanf("%s %s", str_1, str_2)!=EOF)

into this:

Code: Select all

while(scanf("%s %s", &str_1, &str_2)==2)

And what is count doing here?

Code: Select all

printf("No carry operation.\n", count);

Wish you good luck
