## Description
|
|||
|
|
<section id="description"> Thue-Morse序列{Tn}是满足以下条件的二进制序列：T0 = 0T2n = Tn T2n + 1 = 1-Tn <p> {Tn}的前几个术语如下：01101001100101101001011001101001 .... </p><p>我们将{An}定义为整数的排序序列，使得每个元素的二进制表达式在{Tn}中显示为子序列。例如，十进制数18以二进制表示为10010。 10010出现在{Tn}（T8到T12）中，因此18是{An}的元素。十进制数14以二进制表示为1110。 1110永远不会出现在{Tn}中，因此14不是{An}的元素。 </p><p> An的前几个术语如下：n0123456789101112 ... An012345691011121318 ... </p><p>我们还可以验证A100 = 3251和A1000 = 80852364498。 </p><p>找到最后9位数。 </p></section>
