## Description
|

<section id="description">我们可以很容易地验证Pascal三角形的前七行中的所有条目都不能被7整除： <p> 1 </p><p> 1 </p><p> 1 </p><p> 1 </p><p> 2 </p><p> 1 </p><p> 1 </p><p> 3 </p><p> 3 </p><p> 1 </p><p> 1 </p><p> 4 </p><p> 6 </p><p> 4 </p><p> 1 </p><p> 1 </p><p>五</p><p> 10 </p><p> 10 </p><p>五</p><p> 1 1 </p><p> 6 </p><p> 15 </p><p> 20 </p><p> 15 </p><p> 6 </p><p> 1然而，如果我们检查前100行，我们会发现5050个条目中只有2361个不能被7整除。 </p><p>找到Pascal三角形的前十亿（109）行中不能被7整除的条目数。 </p></section>
