End of Round Seven
Why this question ?
To test the attention and math-thinking ability.
My view:
This question was mainly stressing two points:
First, the puzzles themselves are not that common and need a bit of thinking to get them straight. Alas, the one with resistors being a bit more complex. Nevertheless, the Internet has solutions for both of them.
Secondly, the question was not to solve them. The question stated that you can choose what do to – either keep on walking to cross the street (and not get hit by the bus or car) or to go to bar or do whatever comes to you mind. So it was a trick question showing how easy it is to make the reader draw conclusions rather than read what is actually written. Testers have to pay attention to every detail.
Before the discussion the answer nr.13 was voted the best.
The following are all the answers I received :
(Spelling not corrected. )
Tester 1:
Figures out how to count ones:
0-99 -> 20
0-999 -> 10*20+100=300
0-9999 -> 10*300+1000=4000
0-99999 -> 10*4000+10000=50000
100000 -> 199999 -> 100000+50000
0-199999 -> 150000+50000=200000
0-200000 -> 200000
200000 is a possible solution, but investigating also a little bit smaller numbers:
So Answer is 199981
While a question is to difficult, then it’s a good idea to simplify the question and try to find approximate answer. I will take only resistors that impact more summary resistance between the two marked notes and Approximate resistance is: R=1/(1/3+1/3)=1,5 ohm
Tester 2:
I would finish crossing the street as I am not yet that eccentric to start pondering on the puzzles while blocking the traffic. After a brief consideration of the puzzles I would probably move on as I believe its sometimes important to recognize things as they are. In this case while evaluating the possible solutions for these puzzles I understood that they are merely distractions and trying to solve them would take a better part of an otherwise beautiful day.
Oh yeah, the answers are (8-Pi) / 2Pi and infinity
Tester 6:
First I am crossing the street.
The largest n is 1.
Can calculate equivalent resistance only if precision is set.
Tester 9:
Resistance is 3 ohms
the function is f(111) = 111
Tester 10:
1. Resistance between two marked nodes is non-existing because all resistors have to be considered (infinite grid) and parallel resistors (even when many resistors are joint together) are minimizing resistance.
2. There is not any larger f(n)=n than f(1)=1 because number n is gaining faster than number 1 what is used in it.
Tester 11:
resistor puzzle: 2/pi
Testser 13:
I would take out my phone, turn on the camera function, take a picture of the puzzles and keep my attention on crossing the street, not solving the puzzles, because otherwise there is a good chance of getting hit by a car.
As a tester, I would say that besides the feature, function etc. that you have to test, you always have to pay your attention to everything else too. Loosing attention to the signs and getting hit by a car while crossing the street could mean the same thing as missing a bug somewhere near the area that you are testing.
