I tried to code up the calculation of the bearings, and I'm getting some weird answers compared to the provided output. Problem is, I think my output is right and the supplied output is wrong!
Consider: If I'm at 0,0 facing 90 degrees, and there's a ship at 10,10 then the bearing should be 315 degrees, yes? But the problem says 90. Why is that?
Well I have to go but hopefully I've described the problem well enough.

Boy, sure helps to read that problem description eh? That really changed things for the better. Now, I've coded it all up and it does the test data perfectly. For all floating point operations I use an epsilon value of 10^(-7), just as it says. But I still got WA.
Here are some of the relevant functions I've used. Could any of these be the problem?
[cpp]
#define EPSILON 0.0000001
#define PI 3.1415926536
/* double comparison with compensation for rounding errors */
int compare(double a, double b)
{
if (fabs(a - b) < EPSILON)
return 0;
if (a < b)
return -1;
return 1;
}
/* Given degrees, returns radians */
double radians(double degrees)
{
return degrees / 180.0 * PI;
}
/* Given radians, returns # of degrees 0 <= d < 360 */
double degrees(double radians)
{
double d = radians / PI * 180.0;
while (compare(d, EPSILON) < 0)
d += 360.0;
while (compare(d, 360.0) >= 0)
d -= 360.0;
if (compare(d, 359.995) >= 0 || compare(d, EPSILON) <= 0)
return EPSILON / 10;
return d;
}
/* True if the two angles (in degrees) fall within max_diff degrees of each other */
bool degree_compare(double a1, double a2, double max_diff)
{
double d = fabs(a1 - a2);
if (compare(d, max_diff) <= 0)
return true;
if (compare(a1, a2) < 0)
a1 += 360.0;
else
a2 += 360.0;
d = fabs(a1 - a2);
bool bReturn = compare(d, max_diff) <= 0;
return bReturn;
}
/* Finds the actual distance between two points given their x- and y-distances */
double dist(double delta_x, double delta_y)
{
return sqrt(delta_x * delta_x + delta_y * delta_y);
}
[/cpp]

I think if we assume ships as segment then in segment we have 4 light that if we see ship from up (0 course) or down (180 couse) then lights are collinear and we should sort them.
otherwise if we see ship from left of right we can sort light from left to right.
this is the main point of this problem, I think. but I got WA if some body have got any I/O please write it.
thanks.

more I/O?
anybody can provide more I/O?
thx in advance

I get the following output for the set above:
Here's some input I have lying around, which I used to solve the problem. Some of these cases are random-generated, and might be less useful (for instance, too many "Light not visible".)

***************************************************************hi
I have some concern here:
1) if the bearing is 359.995 < 0.00 but the output should be 0.00, then what is its light configurations?
Green Masthead Red or Green Red Masthead?
2) if the bearing is 0.001 > 0.00 but the output should also be 0.00, then what is its light configurations?
Green Masthead Red or Masthead Green Red?
thx in advance

203 - Running Lights Visibility Calculator
I have tried to solve this problem out...
Although, the only thing left in my code right now (Which is still WA) is the calculation of bearings correctly. I am very uncertain as to how the bearing can be calculated, although it should begin from the other ships towards your ship.
I come up with weird results in the ships.fBearing (which is the bearing of all the respective ships), because I am quite unsure as to how you compute for the bearing correctly.
Any ideas? Thanks in advance!

Code: Select all
fy = fAbs (own_ship.yCor - ships[i].yCor);
fx = fAbs (own_ship.xCor - ships[i].xCor);
if (fx != 0)
fTemp = fy / fx;
else
fTemp = 0;
fAngle = atan(fTemp) * 180 / PI;
ships[i].fBearing = ???????? // Still unsure here
ships[i].fDistance = distance(ships[i].xCor,own_ship.xCor,ships[i].yCor,own_ship.yCor);Any ideas? Thanks in advance!
Re: 203 - Running Lights Visibility Calculator
Okay, I am not really certain if the reason for my WA is because of how I would format the output, or not. Maybe it has something to do with my bearings or not.
Someone please verify my output?
Input
Output
Here is how I format my output:
Also, the PI I am making use of is 3.14159265358979323846 instead of the 2*acos(0.0), as for some odd reason I get odd results when I make use of the latter.
Someone please verify my output?

Re: 203 - Running Lights Visibility Calculator
Okay, I've decided to return to this problem...I basically re-did everything, noting that this problem is straight forward.
I've tried all the sample I/O in this thread, and they all match the output, but I keep getting WA!
Here is my code. I'm posting it for anyone's info. Basically, it's a very straight forward problem where you calculate the ships and their locations, their bearings, and then the lights that are visible. Could anyone tell me where it is failing or if there is something preventing it from getting AC? I took into consideration using long double for the bearings as previously mentioned here.
Here's some sample I/O which I clarified w/ uDebug
