My native language is not English,but usually I can understand what the problem mean.However, for problem 108,i.e. Star Medals, I can't understand what the follows mean:
Suppose the star has N rays (each ending with a point) and its line segments connect the points with the step of T. As an example you see above the typical pentagram - the star with 5 points connected with the step of 2
What does the connected with the step of 2 mean?Thank you in advance.
Hi! thanks for your question.
Step is how we calculate to which point the line should go next. E.g. if we have 7-point star, step of size 1 means that index of
the point is increased by 1 each time, so we connect 1-2-3-4-5-6-7-1
. If it is 2 we connect them like 1-3-5-7-2-4-6-1
etc.
The page should have a small demo above the text where you can try different values for number of points and for step (e.g. 7 1
,
then 7 2
, then 7 3
) to get better idea if my explanations are clumsy.
thank you... you should include this explanation in the problem
only by viewing the sequence above we se that the solution can be resumed in a very simple formula thanks again
