I think it will be good if you remove your code after getting accepted.

I am sorry.I have removed it.

For code 1 on the sample input you're printing extra blank lines at the end.

For code 1 on the sample input you're printing extra blank lines at the end.

Ok, I also noticed it when I check output for sample input. But couldn't fix it

But whats wrong with 2nd code? It looks fine for different cases, but why getting WA? Please help me for 2nd code.

[brianfry713]

For the 1st code change line 10 to:
if(s==0 && num[0]=='0' && num[1]=='\0')

For the 2nd code try input: 1 0

Thanks, bryanfry713, got AC.

I have tried everything, but still getting "wrong answer"

My program seens alright... Did a lot of testing and couldn't find any error;

- I'm considering leading zeros (printing them)
- I'm printing the blank columns between digits
- I'm also printing new lines after the numbers
- I've read in a topic that printing two new lines in the last output could solve the problem... No luck...

Plz can anyone help? here is my code ...

Code: Select all

REMOVE AFTER AC :D

Use code tags.

Change input reading to avoid WA.

Code: Select all

string n;

int s,i,j,l, N;

while(1)
{
    cin >> s >> N;

    if (N==0 && s==0)
        break;

    n = to_string(N);

    for (l = 0; l < (2 * s + 3 ); l++)
    ..

It will give PE. Check spaces and newlines to avoid PE. I don't want look at your code if you don't use code tags

I keep getting presentation errors, can someone identify my error? I can't seem to figure it out.

Here is my code:

Output a blank line after each number, including the last one.

[pakosh]

GOT WA for some reason. Any hint? Tried all inputs and every output is same (compared with https://www.diffchecker.com/diff).

Problem solved. There is an example how I had to change my reading

Code: Select all

while (cin >> s && getline(cin, number) && !(s == 0))
{
	int start = 0;
	while (start < number.length() && (number[start] > '9' || number[start] < '0'))
		start++;
	int end = start + 1;
	while (end < number.length() && number[end] >= '0' && number[end] <= '9')
		end++;

	number = number.substr(start, end - start);
        ...
}
