488 - Triangle Wave

[Iwashere]

Can anyone help me with my code. I tried it and it looked alright, but i got WA

Code: Select all

#include <stdio.h>

int amp, fre, no, i, l;

int main(){
scanf ("%d",&no);
for (; no>0; no--){
	scanf("%d %d",&amp,&fre);
	for (; fre>0; fre--){
		for (i=1; i<=amp; i++){
			for (l=i; l>0; l--){
				printf("%d",i);
			}
			printf("\n");
		}
		for (i=amp-1; i>1; i--){
			for (l=i; l>0; l--){
				printf("%d",i);
			}
			printf("\n");
		}
		if ((no==1)&&(l==0)&&(fre==1)){
			printf("1");
		}
		else{
			printf("1\n\n");
		}
	}
}
return 0;
}

Just change the part
[c]
}
for (i=amp-1; i>1; i--){
for (l=i; l>0; l--){
printf("%d",i);
}
printf("\n");
}
[/c]

with
[c]
}
for (i=amp-1; i>=1; i--){
for (l=i; l>0; l--){
printf("%d",i);
}
printf("\n");
}
printf("\n");
[/c]

And remove the part
[c]
if ((no==1)&&(l==0)&&(fre==1)){
printf("1");
}
else{
printf("1\n\n");
}
[/c]

And after the part
[c]
scanf("%d",&no);
[/c]
put
[c]
if(k) printf("\n\n");
else k=1;
[/c]
So you have to add one more variable.
Good Luck!!

Hey, I got AC, thanks for your help!

i got WA and WA but i tried and tried
please please help me!!!!![cpp]
#include <iostream>
#include <stdio.h>
using namespace std;

while(cin>>amp>>fre)
i = i+1;
temp = i--;
for(i = 0; i < temp; i++)

the problem is a multiple input problem ( blue tick ) u must consider this.

[claire yan]

thanks a lot
i have already got AC
^^

[Admus]

I don' know what is wrong with it

Code: Select all

const
  tab:array[1..9] of string=
  ('1','22','333','4444','55555','666666','7777777','88888888','999999999');
var
  a,i,q,n,m,j:longint;
begin
  while not eof do
  begin
  readln(n);
  readln(m);
  if n>0 then
  for i:=1 to m do
    begin
      for j:=1 to n do
        writeln(tab[j]);
        for j:=n-1 downto 1 do
           writeln(tab[j]);
        if i<>m then
          writeln;
    end;
  end;
end.

Here is my code:

[c][/c]

I can't see what is wrong with it!
if someone knows...pleas help me

[shamim]

This is a blue tick problem.
That is the first line of input is the number of test cases, eventhough this is not shown in the sample input.

Thank you Shamin!
I finally got AC!

good bye!!!!

can someone please help me

Hmm, I didn't completely see your code, just a glance... It seems that you've not handled the multiple input case. Note that if u have an earlier version of problemset, the problem was marked as a blue flag problem there.

[Fuad Hassan_IIUC(DC)]

plz help me out.

#include<stdio.h>
#include<iostream.h>
int main()
{
int a,f,i,j,k,l,m,flag;
cin>>a>>f;

flag=0;
for(i=1;i<=f;i++)
{
if(flag==1)
cout<<"\n";
for(j=1;j<=a;j++)
{
for(k=1;k<=j;k++)
cout<<j;
cout<<"\n";
}
for(l=a-1;l>=1;l--)
{
for(m=1;m<=l;m++)
cout<<l;
cout<<"\n";
}
flag=1;
}

return 0;
}

[emotional blind]

this is a multiple input problem
consider about it
did you not see the blue tick in this problem

[Fuad Hassan_IIUC(DC)]

thank you. i got AC . actually it was my foolish mistake
