488 - Triangle Wave

[wangluofan]

I had submitted this for three times but it still wrong.I'm think there is an error where not discovered.

If you copy and paste the code you've posted in this thread and submit it, the result is AC.

[wangluofan]

Yes,But I had submitted once and got a wrong,but this time,the code hasn't been changed,this is very strange!!

[Sabiha_Fancy]

I am getting wrong answere each time i submit it. I can't find the error.
Please help me

Code: Select all

#include<stdio.h>

int main()
{
int n,f,a,i,j,k,l,m;
scanf("%d",&n);
printf("\n");
for(i=0; i<n; ++i)
{
scanf("%d %d",&a,&f);
if(a==0 || f==0)
{
printf("0\n");
if(i<n-1)
printf("\n");
continue;
}
if(i>0)
printf("\n");
for(j=0; j<f; ++j)
{
m=1;
for(k=1; k<=(2*a-1); ++k)
{
if(k<=a)
{
for(l=1; l<=k; ++l)
{
printf("%d",k);
}
}
else
{
for(l=1; l<=k-(2*m); ++l)
{
printf("%d",k-(2*m));
}
m++;
}
printf("\n");
}
if(j<f-1)
printf("\n");
}
if(i<n-1)
printf("\n");
}
return 0;
}

Don't print a blank line at the beginning of the output.

Please help me ,,Getting wrong ans..problem no. 488 ..Triangle wave

here is my code

#include <iostream>

using namespace std;

int main()
{
int amp,fre,i,n,j,v,b;
cin>>n;
for(i=1;i<=n;i++)
{
cin>>amp>>fre;
for(j=1;j<=fre;j++)
{

for(int k=1;k<=amp;k++)
{

for(int l=1;l<=k;l++)
cout<<k;
cout<<"\n";

}
for(v=amp-1;v>=1;v--)
{

for(b=1;b<=v;b++)
cout<<v;
cout<<"\n";
}
cout<<"\n";

}
}

return 0;
}

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

my code.
#include <iostream>
using namespace std;
int main(){
int T,A,f,i,j,k,l;
cin>>T;
cout<<"\n";
for(i=1;i<=T;i++){
cin>>A>>f;
if(A>9){break;}
if(A>0&&A<=9){
cout<<"\n";
for(j=1;j<=f;j++){
for(k=1;k<=A;k++){
for(l=1;l<=k;l++){
cout<<k;
}
cout<<"\n";
}
for(k=A-1;k>=1;k--){
for(l=1;l<=k;l++){
cout<<k;
}
cout<<"\n";
}
cout<<"\n";
}
}
}
}

what is wrong with my code?

Code: Select all

#include <cstdio>

int main()
{
	long n;
	scanf("%ld",&n);
	for (long i = 0; i <  n; i++)
	{
		if (i != 0) printf("\n");
		long a, f;
		scanf("%ld%ld",&a,&f);
		for (long j = 0; j <  f; j++)
		{
			if (j != 0) printf("\n");
			for (long k = 1; k <= a; k++)
			{
				for (long l = 0; l < k; l++)
					printf("%ld",l+1);
				printf("\n");		
			}
			for (long k = a-1; k >= 1; k--)
			{
				for (long l = 0; l < k; l++)
					printf("%ld",l+1);
				printf("\n");
			}
		}
	}
	return 0;
