Make large size of your array(10009) then get acc..

Thanks, I got WA instead :|
Some tests please?

I got one RTE as well during the real time contest. I thought this line "Both numbers are between 0 and a googol (10^100) to the power of a hundred." meant the input is in the range [0, 10^100] and interpreted the last portion of the sentence as an emphasizer of the portion in bracket. But this was supposed to mean googl^100, ie (10^100)^100.

And about test cases:
Each case of input is just 2 numbers A B and you are asked to find A-B. Surely, you don't need help from others. You can make test cases on your own!! Just make few random cases for small numbers that fit in 32-bit integer. And compare your real code with this code " scanf("%d %d", &A, &B); printf("%d\n", A -B); "

One critical case that comes to mind is "10000 1" and that should output "9999".

I got ACed ! Thanks a lot, you're right, I read the statement very carelessly ~~

I am not able to figure out the failed test case.
my array is 10009 digits.

Thanks.

Thanks Brian, I will have to modify the code for considering -ve number too...I will try that..

You can solve this in just a few lines of JAVA.

[gr81]

thanks, with previous code I failed one test case...i got AC. I don't know ABC of java....

Replying to follow the thread.

Problem description says

For each test case, there is a line with two positive integer numbers, A and B, corresponding to the
benefits and the costs, respectively. Both numbers are between 0 and a googol (10^100) to the power of
a hundred.

Statement that A and B are positive is a mistake. They are non-negative. Between 0..10^10000.

Thanks Brian, I will have to modify the code for considering -ve number too...I will try that..

So some inputs posted by gr81 and brianfry713 are invalid. Input numbers should be non-negative. There is no need to consider negative numbers.

I deleted my post with invalid input.
