I'm puzzled. Now 2 people have submitted solutions that agree with the test suite, but the test suite seems wrong to me! Looking at all 3 'yoonir' problems for a radius of 10 units:
Program Points test_suite my_calc
yoonir_02 5 112.27 112.26
yoonir_04 6 173.20 173.21
yoonir_06 7 108.34 210.17
How would it be possible that in going from a 6 pointed star to a 7 pointed star, the area drops from 173.2 to 108.3?
in the figure, the available area inside the polygon of a 7-pointed star has actually decreased compared to 6-pointed star .isn't it?
Gosh, that seems to be right! I thought my solution was good for all N, but I can see from that figure that it's not. Thanks for the tip.
I have discovered something! While there is just one way to draw a five-pointed star or a six-pointed star, there are actually two ways to draw a seven-pointed star. One of them has an area much larger than the other.
yes i saw that later on utube..didn't know that before
It was actually unintentional. I originally intended to submit only the 1st problem of yoonir(which is a 5 pointed star) but then it suddenly came to mind what about a 6/7 pointed star. Tried to calculate one by one.
a generalized problem of an n-pointed star would have been gd.
