I cant understand. why submission error?
Code: Select all
#include <stdio.h>
int printing(int x)
{
int i;
for ( i = 0; i < x; i++)
printf("%d",x);
printf("\n");
return 0;
}
int main()
{
int tst_cas, f, w, i, j, triger =0 ; // w for Amplitude, f for Frequency
scanf("%d", &tst_cas);
while( tst_cas--)
{
scanf("%d %d",&f,&w);
w= w+1;
for ( j = 1; j < f; j++)
{
if(triger) printf("\n"); /* we need not print new line after the last output. so I use it here.
the condition controls it not to print new line for first time output */
for(i=1; i<=w; i++)
printing(i);
for(i=w-1; i>=1; i--)
printing(i);
triger =1;
}
}
return 0;
}

i=1;
scanf("%d%ld",&Amp,&Fre);
while(i<=Fre)
{
for(K=1; K<=Amp; K++)

I can't be any more specific than that. The last line of the output should have the new line character '\n' at the end of it.

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

Your
"WA" code is accepted code. Problems with copy/paste?
Don't post full accepted code just post necessary part.

The input begins with a single positive integer on a line by itself indicating the number of the cases following
According to problem description you should read a number of test cases
once, loop is unnecessary. Your loop prints extra blank line at the beginning. Don't print extra blank line after last wave form.

I can't find the problem of my code. Its showing wrong answer.
Here is the code:
Code: Select all
#include<iostream>
using namespace std;
int main()
{
int i,j,k,amplitude,frequency,test_case;
cin>> test_case;
cin>>amplitude>>frequency;
while(test_case--){
for(k=1;k<=frequency;k++){
for(i=1;i<=amplitude;i++){
for(j=1;j<=i;j++){
cout<<i;
}
cout<<endl;
}
for(i=amplitude-1;i>=1;i--){
for(j=1;j<=i;j++){
cout<<i;
}
cout<<endl;
}
if(k<frequency)cout<<endl;
}
}
return 0;
}
