488 - PRESENTATION ERROR!

[TripShock]

this program seems t conform to all the rules but still gets PE! help!

Code: Select all

#include <iostream>

using namespace std;

int main()
{
    short a = 0;
    short f = 0;
    short n = 0;
   
    cin >> n;
   
    while(n)
    {
        cin >> a;
        cin >> f;
   
        for(char i = 1; i <= f; i++)
        {
            for(char j = 1; j <= a; j++)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                if(a != 1)
                    cout << endl;
            }
            for(char j = a - 1; j >= 1; j--)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                cout << endl;
            }
            if(!(i == f && n == 1))
                cout << endl;
        }
        n--;
    }
   
    return 0;
}

Check the output description:

The outputs of two consecutive cases will be separated by a blank line.

NOTE: There is a blank line after each separate waveform, excluding the last one

Remove your code after you get AC.

Input:
1

3
2

Output:
1\n
22\n
333\n
22\n
1\n
\n
1\n
22\n
333\n
22\n
1\n


Should I remove the last '\n' ?

Should I remove the last '\n' ?

Nope. In fact this is ok. Apparently I overlooked one line of code in your program which does this. But then again to get AC you have to print a blank line after each triangle wave, which is exactly what my AC program (no PE) did. I know what my AC program did does not really conform to the output description. I will leave a post in the Bugs and Suggestions forum regarding this.

I don't get it! Now i'm getting WA!!!

Code: Select all

#include <iostream>

using namespace std;

int main()
{
    short a = 0;
    short f = 0;
    short n = 0;
   
    cin >> n;
   
    while(n)
    {
        cin >> a;
        cin >> f;
   
        for(char i = 1; i <= f; i++)
        {
            for(char j = 1; j <= a; j++)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                cout << endl;
            }
            for(char j = a - 1; j >= 1; j--)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                cout << endl;
            }
            if(!(i == f && n == 1))
                cout << endl;
        }
        n--;
    }
   
    return 0;
}

Code: Select all

code is deleted after AC


tankyou very much for the example i got AC.

[Oronno]

I have done this proble, and there is no space after last output.
But i still getr the presentation error.
Why???????
check it.

Code: Select all

Code has removed

[helloneo]

You forgot '\n' at the end..
Just try to follow TripShock's output format above..

[Oronno]

Ohhh...thanks.
I get AC.

[john_locke]

this problem drove me toward madness i got 20 presentation errors from judge tried all the combinations after reading previous post so plzzz help me

DELETED after -AC
thanx

[ranacse05]

Why output Limit E...??????


*************code removed***************

[Jan]

Check your code carefully.

Code: Select all

for(i=0;i<num;i++)
    ...
    for(k=0;k<b;k++)
        ...
        for(i=0;i<a;i++)  // i again ???
            ...


Hope it helps.

[ranacse05]

Why PE ?
plz help me
#include "stdio.h"

int main()
{
int a,b,i,j,k,num;


while(scanf("%d",&num)==1)
{
for(i=0;i<num;i++)
{
scanf("%d %d",&a,&b);
printf("\n");
for(k=0;k<b;k++)
{
for(i=0;i<a;i++)
{ for(j=0;j<i+1;j++)
printf("%d",i+1);
printf("\n");
}

for(i=a-2;i>=0;i--)
{ for(j=0;j<i+1;j++)
printf("%d",i+1);
printf("\n");
}
printf("\n");
}
printf("\n");

}
}
return 0;
}
