## Description
<section id="description"> Рассмотрим множество S (r) точек (x, y) с целыми координатами, удовлетворяющими | x | + | y | ≤ r. Пусть O - точка (0,0) и C - точка (r / 4, r / 4). Пусть N (r) - число точек B в S (r), так что треугольник OBC имеет тупой угол, т. Е. Наибольший угол α удовлетворяет 90 ° &lt;α &lt;180 °. Так, например, N (4) = 24 и N (8) = 100. <p> Что такое N (1,000,000,000)? </p></section>
