any tricky test cases???
the following is my code:

[cpp]

#include<stdio.h>
void main(void)
{
double x1,x2,x3,x4,y1,y2,y3,y4,a1,b1,a2,b2;
double px,py;
int i,n,check;

while(scanf("%d",&n)!=-1 && n>0)
{
printf("INTERSECTING LINES OUTPUT\n");
for(i=1;i<=n;i++)
{
scanf("%lf%lf%lf%lf%lf%lf%lf ...

Wrong Answer 0:00.004 64 23448 C++ 122 - Trees on the level

sigh.....
I send again, and wa again...

but thx anyway, Dominik
It must take you a lot of time to test my code
thx again~~

another way to avoid TLE

you can save the results in an array after calculating
then get the input and output the corresponding answer
like the following:

[c]
#include<stdio.h>
void main(void)
{
int n,i,ans[13];

for(i=0;i<13;i++)
{......}

while(scanf("%d",&n)!=-1 && n>0)
printf("%d\n",ans ...

sorry, i tried what you said, Balon
but it failed.
you can try the input "aAb", and see what happened.

thx anyway

why I got RTE???
who can help me??? :cry:

[c]
#include<stdio.h>
#include<string.h>
#include<ctype.h>
void main(void)
{
char s[10000];
int i,j,count;

while(gets(s))
{
count=0;
for(i=0;i<strlen(s);i++)
{
if((s >='A' && s <='Z') || (s <='z' && s >='a'))
{
while(((s >='A' && s <='Z') || (s ...

thx, epsilon0....
I will try to make my code more readable.

epsilon0....I totally agree with you
and luckily, my code posted above just did what you mentioned
(you can take a look......though it's not easy to understand... )

but to my surprise, I got WA.....
this is why I post my code here.......T_T....

sorry~~
I can't use private message....
can you give me your email??
my email is atias@pchome.com.tw
thx~~

thx for your advice, dominik...
you are right...I didn't pay attention to this.....

besides, I think my code can run in a C compiler, like gcc
I just use vc++ to code, but in fact, I use C syntax....

thx for help~~

I don't know why I got OLE...
can anyone help me??



#include<stdio.h>
#include<string.h>
#include<ctype.h>
void main(void)
{
int i,j,c,temp;
char s[5000],t;
void perm(char a[5000],int k,int n);
while(scanf("%d",&c)!=-1 && c>0)
{

for(temp=1;temp<=c;temp++)
{
scanf("%s",s);
for(i=strlen ...

hmm...dominik
here's my code now
I think it will do what you said, but I got another WA..... :(
why~~

[c]
#include<stdio.h>
#include<string.h>

void main(void)
{
int i,sum,v[256],count=0,ch;
char c,temp,t[257],ad[257][257];
void tree(char tr[257][257],int n[256],int co);

for(i=0;i<256;i ...

I fix the bug....but still got WA....><


I also find something strange...
can two nodes have the same value??
ex: (5,) (4,L) (4,R) ()
my code will print 5 4 4

thx for help~~

but.....epsilon0,
if I don't misunderstand, I don't think my code would neglect what you metioned.
Can you give me some test cases?
or can you try my code and tell me what's wrong?
thx a lot~

here is my code for 122. I got WA, too.
can anyone give me some test cases or help me with my code???

[cpp]
#include<stdio.h>
#include<string.h>
void main(void)
{
int i,sum,v[256],count=0,ch;
char c,temp,t[257],ad[257][257];
void tree(char tr[257][257],int n[256],int co);

for(i=0;i<256;i ...
