--description--
从1开始并以下列方式逆时针旋转,形成边长为7的方形螺旋。 37 36 35 34 33 32 31 38 17 16 15 14 13 30 39 18 5 4 3 12 29 40 19 6 1 2 11 28 41 20 7 8 9 10 27 42 21 22 23 24 25 2643 44 45 46 47 48 49这是有趣的是,奇数方块位于右下角,但更有意思的是沿着两条对角线的13个数字中有8个是素数;也就是说,比例为8 /13≈62%。如果在上面的螺旋周围缠绕一个完整的新层,则将形成具有边长9的方形螺旋。如果继续这个过程,那么沿着两条对角线的素数比首先低于10%的方形螺旋的边长是多少?
