 蛮好玩的一串数,
 就这么 0 与 1 简单的组合,
 既不会出现连续3个0,也不会出现连续3个1,
 0 的两边肯定是 11,  1 的两边肯定是 00,
 ......
 好像还找不到循环!
 \(n=15,16,17,......\bigg[\ \ \ \ \ \bigg]\)表示四舍五入
 
 \(a(n)=\bigg[\frac{1}{2}\sqrt{2n^2+2n+1\ \ }\ \bigg]-\bigg[\ \sqrt{n^2+n-\bigg(\frac{1}{2}\bigg[\sqrt{2n^2+2n+1\ \ }\ \bigg]+\frac{1}{2}\bigg)^2\ \ \ \ }\ \ \ \ \bigg]\)

 各位网友!可有类似的资料?
