Some nights when I cannot sleep, I lay there, staring at the clock. And my mind starts racing. Let's see if we can get yours spinning too.
The puzzle should not be too hard, in fact you may be able to solve it from the comfort of your bed! Plus, by definition, this should require only 12 hours to solve if you choose the lazy method!
Don’t blame me, if you never look at your alarm clock the same way.
A = What time of day is the “brightest” time? (Treat as a 3 or 4 digit integer.)
B = What time of day is the “darkest” time? (Treat as a 3 or 4 digit integer.)
C = Which LED segment is lit the longest time in any 12 hour period? (use figure below)
D = What percentage of the time (in any 12 hour period) is that LED segment on for?
E = What percentage of the time (in any 12 hour period) are the two LED segments, that are on the least, on for?
F = Two LED segments are on for 50% of the time (in any 12 hour period), select the higher segment number.
The final is located at:
N 42 WW.XXX
W 077 YY.ZZZ
WW = B – (F * 3) - 8
XXX = (D * 5) + (E * 4) – C – 2
YY = B – D + F + 2
ZZZ = A – B - 6
Assumptions:
This is a standard 12 hour (not 24 hour military time), seven segment LED clock.
The clock is set and running, not just flashing 12:00.
All segments are the same size and brightness when turned on.
There is no auto-dimming feature, the LEDs output constant brightness regardless of ambient lighting.
There are no power outages, brown-outs, power surges or lightning strikes.
No tricks, just a simple counting.
