| ## Description
 | ||
| <section id="description"><p> <a href="https://en.wikipedia.org/wiki/Charles_Babbage" title="wp:Charles_Babbage">Charles Babbage</a> ,展望他的分析引擎能解决的各种问题,给出了这个例子: </p><blockquote>什么是正方形以数字269,696结尾的最小正整数? </blockquote><p> - 巴贝奇,致鲍登勋爵的信,1837年;见Hollingdale和Tootill, <i>电子计算机</i> ,第二版,1970年,p。 125。 </p><p>他认为答案可能是99,736,其平方是9,947,269,696;但他无法确定。 </p><p>任务是找出巴贝奇是否有正确的答案。 </p><p>实现一个函数来返回满足Babbage问题的最小整数。如果巴贝奇是对的,返回巴贝奇的号码。 </p></section>
