So, i have tryed a lot of changes, but I am always geting WA
Can anybody help me to find what is wrong in my code? Please?

Code: Select all

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int n, amp, freq, i, j, k, l;
    
    scanf("%d", &n);
    while(n > 0) {        
        scanf("%d %d", &amp, &freq);
        for(i = 1; i <= freq; i++) {
            for(j = 1; j <= amp; j++) {
                for(k = 0; k < j; k++) {
                    printf("%d", j);
                }
                printf("\n");
            }
            for(k = amp - 1; k > 0; k--) {
                for(l = 0; l < k; l++) {
                    printf("%d", k);
                }
                if(k > 1) {
                    printf("\n");    
                }
            }
            if(i < freq) {
                printf("\n\n");    
            }
        }
        if(n != 1) printf("\n\n");
        n--;
    }
    system("pause"); /*uncomment it before sending*/
    return 0;
}

Thank you all

k=j;
if(j>a)
k=(a-(j-a));
for(i=0;i<k;i++)
cout<<k;
cout<<endl;
}
if(l<f-1)
cout<<endl;
}
}
int main()
{
long long n,a,f,i,j;

for(i=0;i<n;i++)
{
cout<<endl;

if(a>9)
return 0;
cin>>f;
wave(a,f);
if(i!=n-1)

You can use the search option [located at the top right of the screen] to find existing threads of this problem! You will find lots of discussions there.
- Don't create a new thread if one already exists.. and also make sure you use an informative subject. "Help me please" doesn't actually say much about the problem you are having trouble with.

Good Luck!

i dont know where the problem pleas help
#include <iostream>
using namespace std;

int main()
{
int *mag;
int * freq;

int cases=0;
int count=0;
cin>>cases;
cout<<endl;
mag= new int [cases];
freq=new int [cases];

for(int i=0;i<cases;i++)
{
cin>>mag;
cin>>freq;

cout<<endl;
}

int y=0;

while(y<cases)
{
while(count<freq[y])
{

for(int i=1;i<mag[y]+1;i++)
{
for(int j=0;j<i;j++)
cout<<i;
cout<<endl;
}

for(int i=mag[y]-1;i!=0;i--)
{

You are printing too much new lines.

This Code always gives me a wrong answer please I want to know why

Code: Select all

    
#include <iostream>
using namespace std;

void Test(int ambitude,int freq)
{
 for(int i=0;i<freq;++i)
    {
         for( int s=1;s<=ambitude;++s)
            {
              for(int w=1;w<=s;++w)
                 cout << s ;
               cout << endl;     
            }
          for( int s=ambitude-1;s>=1;--s)
            {
              for(int w=1;w<=s;++w)
                 cout << s;
                 cout << endl;
            }   
            if(i!=freq-1)
            cout << endl;    
    } 
}
int main(int argc, char *argv[])
{ 
    int* ambitude;
    int* freq;
    int number;
    cin>>number;
    cout << endl;
    ambitude=new int[number];
    freq=new int[number];
    for(int i=0;i<number;++i)
    {
    cin>> ambitude[i] >> freq[i];
    cout << endl;
    }
    for(int i=0;i<number;++i)
    if(ambitude[i]<=9)
    {
       Test(ambitude[i],freq[i]);
    }

Can't figure out what's wrong with my answer. I don't print a blank line at the top of my output, I only output a blank line between frequency loops and cases, and I don't print anything after the last number of the last frequency loop of the last case. I'm using cin and cout, but I still come in with time to spare (~1.4s).

Code: Select all

Got AC...

You should print '\n' after the last test case..
Remove your code if you get AC

I cannot find what my problem is

Can anyone help pleasure ...

Hi dewsworld

You have a problem with '\n' newline.

For this input

Code: Select all

your output

Code: Select all

where it should be

Code: Select all

Good luck!

finally i got AC!

The input begins with a single positive integer on a line by itself indicating the number of the cases following, each of them as described below. This line is followed by a blank line, and there is also a blank line between two consecutive inputs.

i didnt do bold part: but i got AC!
