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%lf",&x1,&y1...

You can see here for some tips

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[n-1]); } [...

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 <='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(s);i>0;i--) for...

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++) v =0; whil...

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++) v =0; wh...
