I tested your code and only got a blank line and then an infinite loop for the sample input. I used scanf to solve this problem.

Post your questions to an existing thread about a problem. Use the code block for better readability.

i got WA,and my output is the same as the answer, i submit many times, but it always WA!!
this is my code:

#include <iostream>
#define MAXAMP 9
using namespace std;
int main()
{
int n,Amp,Fre,elem,k,l=0,m=0;
while(cin>>n)
while(n--)
{
cin>>Amp>>Fre;
if(Amp>MAXAMP||Amp<=0)
break;
//if(l=0;
if(n!=0)
m=Fre;
else
m=Fre-1;
for(int i=0;i<Fre;i++)
{
for(int j=1;j<=Amp;j++)
{
k=elem=j;
if(l!=0)
cout<<'\n';
l=1;
while(k--)
cout<<elem;
}
for(int j=Amp-1;j>=1;j--)
{
k=elem=j;
if(l!=0)
cout<<'\n';
while(k--)
cout<<elem;
}
if(m--)
cout<<'\n';
}
}
return 0;
}


plz help me,Thanks!

Missing newline at end of output.

Hi! I always got TLE. Can anybody tell me what's making it slow? Here's my code:

#include <stdio.h>

int main() {
int amp;
int freq;
int Tamp;
int a;
int b;
int c;
int d = 1;
int e = 0;
int temp;

while (scanf("%d",&amp) != EOF) {
scanf("%d",&freq);
Tamp = (amp * 2) - 1;
for (a = freq;a > 0;a--) {
d = 1;
e = 0;
for (b = Tamp;b > 0;b--) {
for (c = d;c > 0;c--){
printf("%d",d);
}
if (d == amp) {
e = d;
}

if (e > 0){
d--;
} else {
d++;
}
printf("\n");
}
if (a != 1) {
printf("\n");
}
}
printf("\n");
}
return 0;
}

Your problem is the way you read the input. Your code doesn't work for the sample I/O.
The input begins with a single positive integer on a line by itself indicating the number of the cases following.

um also getting WA ,,, in this problem ,,, .. here's my code

code removed

[brianfry713]

Don't print an extra newline at the end of the output.

[sonjbond]

Don't print an extra newline at the end of the output.

thanx,,, now i get AC

[wangluofan]

Code: Select all

#include<stdio.h>

int Output(int Amplitude)
{
	int index;
	for(index=1;index<=Amplitude;++index)
	{
			for(int j=0;j!=index;++j)
					printf("%d",index);
			printf("\n");
	}
	for(index=index-2;index!=0;--index)
	{
			for(int j=0;j!=index;++j)
				printf("%d",index);
			printf("\n");
	}
	return 0;
}
int main(void)
{
		int Case,Amplitude,Frequency;
		scanf("%d",&Case);
		while(Case--)
		{
				//scanf("%d%d",&Amplitude,&Frequency);
				scanf("%d%d",&Amplitude,&Frequency);
				for(int j=1;j<=Frequency;j++)
				{
					Output(Amplitude);
					if(Case!=0||j!=Frequency)
							printf("\n");
				}
		}
		return 0;
}

Why this code Wrong?Please help me,Thank you!

[brianfry713]

That is AC code.

[wangluofan]

Really?I'm think so too.But I really got a WA?

[brianfry713]

Submit it again.
