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

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.

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

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.

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);
        ...
}
