488 - Triangle Wave

[emotional blind]

print a blank line between two consecutive cases.

[tajbir2000]

#include<stdio.h>
int main(){
int i,j,n,f,k.l,cas;
scanf("%d",&cas);
while(cas){
scanf("%d %d",&n,&f);
while(f){
for(i=1;i<=n;i++){
for(j=0;j<i;j++){
printf("%d",i);
}
printf("\n");
}
for(k=n-1;k>0;k--){
for(l=0;l<k;l++){
printf("%d",k);
}
printf("\n");
}
f--;
if(f!=0)
printf("\n");
}
cas--;
}

return 0;
}

You must print blank lines between testcases also....

read the problem statement again carefully.....

[f.a.reza]

where is the mistake?i m continuously getting wrong answer
#include<stdio.h>


int main()
{
int i,j,k,l,x,y,n;
scanf("%d",&n);

for(i=1;i<=n;i++)
{ printf("\n");
scanf("%d",&x);
scanf("%d",&y);

for(j=1;j<=y;j++)
{
for(k=1;k<=x;k++)
{
for(l=1;l<=k;l++)printf("%d",k);
printf("\n");
}
for(k=x-1;k>=1;k--)
{

for(l=1;l<=k;l++)printf("%d",k);
if(j!=y||k!=1)printf("\n");
}

if(j!=y)printf("\n");
}



}

return 0;
}

WA here could any one check this pls
#include<iostream>
using namespace std;
int main()
{
int noofcases;
char *s[9]={"1","22","333","4444","55555","666666","7777777","88888888","999999999"};
int flag=0;
cin>>noofcases;
while(noofcases)
{
noofcases--;
if(!flag)cout<<"\n";
flag=1;
int n,f;
cin>>n>>f;
for(int i=0;i<f;i++){
for(int j=0;j<n;j++){
cout<<s[j];
cout<<"\n";
}
for(int j=n-2;j>=0;j--){
cout<<s[j];
cout<<"\n";
}

}
}
return 0;
}

To vinocit
Problem says:

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

See the output format.

Thanks a lot i got AC

[pok]

pls tell me why i'm getting WA..

#include<stdio.h>

int main()
{
long long int n,i=0,k,j,m,p;

scanf("%lld",&n);


while(i<n)
{
printf("\n");
scanf("%lld\n%lld",&m,&p);
printf("\n");

int o=0;

while(o<p)
{
for(j=1;j<=m;j++)
{
for(k=1;k<=j;k++)
printf("%lld",j);
printf("\n");
}
for(j=m-1;j>=1;j--)
{
for(k=1;k<=j;k++)
printf("%lld",j);
printf("\n");
}
o++;
if(o!=p) printf("\n");
}
i++;


}

return 0;
}

i realy need ur help..

[pok]

Why i got WA in this problem ???????
why why why ?
i cant understand ..
pls help me.......

Code: Select all

removed after AC..

[Articuno]

Change this portion of your code:

Code: Select all

      printf("\n");
      scanf("%lld\n%lld",&m,&p);
      printf("\n");

into this:

Code: Select all

      scanf("%lld\n%lld",&m,&p);
      if(i!=0) printf("\n");

That will do.

[pok]

Thanks.. Articuno..
take care..
God bless you..

[tajbir2000]

i have got ac......... i had missed it

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

[sazzadcsedu]

whats wrong with my code??
WA.
#include<stdio.h>


int main()



{

int amp,freq;

int ncase,i,k,l;


scanf("%d",&ncase);

while(ncase>0)

{
scanf("\n\n%d",&amp);
scanf("\n%d",&freq);

for(i=1;i<=freq;i++)

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

{
printf("%d",k);
for(l=1;l<k;l++)

{
printf("%d",k);

}

printf("\n");
}


for(k=amp-1;k>0;k--)

{
printf("%d",k);
for(l=1;l<k;l++)

{
printf("%d",k);

}

printf("\n");
}
if(i<freq)
printf("\n");

}

ncase--;

}


return 0;
}

[Harlan]

Where is the problem??

?

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

main()
{
int t, ax, ay, fx, k = 1, tx = 0, ty = 0;

scanf(" %d", &t);

int a[t], f[t];

printf("\n");

while(tx < t)
{
scanf(" %d", &a[tx]);
scanf(" %d", &f[tx]);
printf("\n");
tx++;
}

while(ty < t)
{
fx = 1;
while(fx <= f[ty])
{
k = 1;
for(ay = 1;ay < a[ty] * 2;ay++)
{
if(ay <= a[ty])
{
for(ax = 1;ax <= ay;ax++)
{
printf("%d", ay);
}
}
else
{
for(ax = a[ty] - k;ax > 0;ax--)
{
printf("%d", a[ty] - k);
}
k++;
}
printf("\n");
}
printf("\n");
fx++;
}
ty++;
}

system("PAUSE");
return 0;
}

Thanks!!!

Anybody could help me getting out of TLE ??
this is my code and please check it out which makes it slow....

Code: Select all

import java.util.Scanner;
public class Main
{
	public static void main (String [] sun)
	{
		Scanner input = new Scanner (System.in);
		int n = input.nextInt();
		int [] num = { 1, 22, 333, 4444, 55555, 666666, 7777777, 88888888, 999999999 };

		int f, i, A, F;
		while (n-->0)
		{
			A = input.nextInt();
			F = input.nextInt();
			for (f=1; f<=F; f++)
			{			
				for (i=0; i<A; i++)
				{
					System.out.printf ( "%d\n", num[i]);
				}
				for (i=A-2; i>=0; i--)
				{
					System.out.printf ( "%d\n", num[i]);
				}	
				System.out.printf ("\n");;						
			}
		}
	}
}

Please reply me as soon as possible....thanx anyway...
