Hello Codeforces, Can anyone help me in the Problem? There is no editorial for these round. I read others codes but it is hard to find out logic from that. Any help will be appreciated. Thanks.

you need to cover the circle from inside with a layer of dots. the count of those is exactly the perimeter of the inside square (n*sqrt(2)*4) where n is the radius = (square side)/2*sqrt(2)
Can you explain more clearly.I am not able to understand how did you come up with formula.
try to draw ce circle on a math paper and search for the solution. Also don't stay too much on a single problem, just skip it and try again later.
