Nice tests!
Suppose, if they (and their modifications) are added, many authors will lose AC (because long double accuracy not enough to pass these tests).

Also it is quite difficult to implement long arithmetic solution here and pass the TimeLimit. The task will be Hard* instead of Hard.

Alexey Re: some tests! // Problem 1415. Mobile Life 16 Mar 2012 06:51

Hi.

I'm not sure, but this test (#2) looks invalid, because:
"Also, we assume that at the points where the segments join, Shpuntik's phone never changed cells and that for each of the stations the curves of change of the signal's level do not pass through these points. And he never went at a tangent to that curves."

The point 20 10 looks like Orange-Red bound of station B.

Could somebody please clarify this point?

Safe Bird 1st question. (There're two kinds of understandings.) [15] // Problem 1415. Mobile Life 1 Nov 2005 13:26

If there're two stations that would give the signal as VIOLET, but one is stronger.
1. we choose the stronger.
2. we choose the one according to their names.

which one is right? anyway, i got wa on 4 on both of the meanings.

Safe Bird 2nd question [11] // Problem 1415. Mobile Life 1 Nov 2005 13:50

If the segment which our hero goes just tangentalled to the curves of change of the current signal's level, should I output twice "Signal Changed...."?

The condition is the same as above, if he just touches the curve of ORANGE, should I output:
Cell changed. CELL_ID:...., SIGNAL_LEVEL:ORANGE
Signal changed. SIGNAL_LEVEL:RED
?

My 6th question: should i use ( char * ) instead off ( unsigned char * ) or vise versa for names?

Michael Rybak (accepted@ukr.net) Re: 6th question [5] // Problem 1415. Mobile Life 26 Nov 2005 18:58

I disagree with you, Fly.

Question 1 - indeed, seems like we should choose the stronger signal, not the best color, but indicator is only able to distinguish between colors, not strengths, so it's a bit unclear.

The answer to question 2 depends on what happends if distance is equal to critical.

Take a look:

1. "If the distance between the phone and a base station is less then a certain value, then the signal is ideal"

2. "If the phone is moved away from a base station further than the threshold distance, then the indicator goes indigo, then blue, green, and so on"

3. "Rc is its threshold distance within which the station's signal is shown by the violet color of the indicator"

These three statements can't be resolved clearly, IMHO. "within" means <=, while "less" means <.

As for question 4, it isn't really clear, because "The phone stays connected to the same station until its signal goes red; then it switches to the search mode and tries to select a new station", so we can't tell whether the phone is in search mode from the very beginning or no. Although this doesn't seem to affect our output, behaviour is poorly described for this problem.

Fly [Yaroslavl_SU] Re: 6th question [1] // Problem 1415. Mobile Life 26 Nov 2005 20:08

Questio #1. I don't know. I tried both and got WA#8.

Question #2. "If the distance between the phone and a base station is less then a certain value, then the signal is ideal".I think its right. "within which" means such as "inside which".

Question #4. "When the phone is being turned on, it selects a station with the strongest signal. If there are several such stations, then the station with the minimal (with respect to the lexicographic order) name of the cell is selected among them." Color isn't take to account.

I agree to *answers* to your questions, but I disagree with reasons.

Indeed, your answers are correct and I got them as well by experimenting. What I claim to be wrong is uncertainty in problem statement; such details should be pointed out.

Denis Koshman Re: 6th question // Problem 1415. Mobile Life 31 Aug 2008 08:26

It probably can be extrapolated from this phrase "Violet corresponds to the strongest signal". But then it turns out that the 1st picked station can be violet only (also _strongest_ signal), and if there is no violet station nearby, it's undefined behavior :D

Safe Bird Incorrect case#3 (And what's more) // Problem 1415. Mobile Life 1 Nov 2005 14:15

There's the line: "Also, we assume that at the points where the segments join, Shpuntik's phone never changed cells and that for each of the stations the curves of change of the signal's level do not pass through these points." in description.

I got wa on 4. And after putting this line to judge whether it suffers the condition above:

if (case_is_wrong) then DIE

I got RE on 3. I think at least case 3 is wrong, or the description is wrong!

Aleksandr Klepinin Re: 1st question. (There're two kinds of understandings.) [1] // Problem 1415. Mobile Life 17 Nov 2005 11:06

If I am not mistaken, base station selection is made ONLY when power indicator shows RED. Otherwise we stay connected to currently selected base station (until power indicator gets RED) even if there is another one with stronger signal.

Safe Bird you misunderstood my question. // Problem 1415. Mobile Life 24 Nov 2005 10:24

i means, while changing channel, which one should be chosen:

if there are two stations providing very strong signal, but the SAME COLOR. i should choose the closer one or according to their names.

in other words, i should choose according to the DISTANCE, or the COLOR of stations?
