Hi.. Surya..
Actually i don't see ur code..but from ur explanation i think something is wrong..
you can forward below this approach..
1.if 4 arm length is equal
if 4 angle is 90 --> square
else ---> Rhombus
2. if (2 * 2)opposite arm length is equal
if 4 angle is 90 --->Rectangle
else ...

I tried using simplest approach:
sort the four position using ccw sorting by cross product
check the 90 degree by using trigonometry:
AC^2 = AB^2 + BC^2 - 2(AB)(BC)cos d
since cos 90 = 0
then AC^2 = AB^2 + BC^2
i check the four side from the position

the following is the check :
1. if all 4 is 90 ...

Can someone help me and see what's wrong with my code? I keep getting WA but i dont know why. Or can someone give me more sample input?



you can check whether you met this condition:
If there is more than one of these best positions then the location with the “minimal” position will be chosen ...

hello, i try this problem using long no double or floating point involved, but i got WA
is there anything I need to concern ?
any one can help me find what make my code WA, thanks
this is my code:

for concern about input in this problem:
there's trailing space in the end of the line for the test case
my code got PE when assuming there's not

There will be an unexpected output in the intToHuruf function
char temp[10] is a local variable, you can't return pointer to this variable since it will be used by other when the process is out of the function

PS: just try to make a more elegant code using array of string like:
const char *map ...

anyone still try this problem?
i tried it using brute force BFS and the result from in I/O in this topic is the same except the path
is there any case I need to concern for?
or there something I miss?
please help, this is my brute force code:
AC
anyone that still WA, you can check if the case when ...

I tried using long too and accepted
it mean the judge computer using 64bit now ?
i tried in the 64bit computer and print sizeof(long) and it return 8 which is sizeof(long long) in 32bit computer

hello can anybody help me?
I've tried all the I/O I found has the same output as my code but still WA
is there anything need to be check?
here is my code:
AC
PS : I should print blank line after each report not between report, such a mistake ..., and check the full string for action not just the ...

well thanks, it doesn't come to my mind
because I just found it to be strange...

My code is a little long. but, Actually, I have already written my BigInteger class. So, I just want to reuse my class.

here is the error :

I have a problem with sizeof struct
with this code

#include <stdio.h>
struct A
{
int a;
short b;
};
struct B
{
int a;
short b,c;
};
int main()
{
printf("%d %d\n",sizeof(struct A),sizeof(struct B));
return 0;
}

how can sizeof( struct A ) and sizeof( struct B ) is 8 ???
can anyone explain ...

Your code isn't working for:
abc^def ghi
well thank you, I don't think there will be a '^' in the input
Maybe. But your code didn't work for a whole family of such similar symbols... the symbol '^' was just an example of one such symbol...
my bad, I was think that there's only character 'A-Za ...
