## Description
|
|||
|
|
<section id="description">对于一些正整数k，存在形式为4t = 2t + k的整数分区，其中4t，2t和k都是正整数而t是实数。 <p>前两个这样的分区是41 = 21 + 2和41.5849625 ...... = 21.5849625 ... + 6。 </p><p> t也是整数的分区称为完美。对于任何m≥1，让P（m）为k≤m的完美分区的比例。因此P（6）= 1/2。 </p><p>在下表中列出了一些P（m）P（5）= 1/1 P（10）= 1/2 P（15）= 2/3 P（20）= 1/2 P（25）= 1/2 P（30）= 2/5 ... P（180）= 1/4 P（185）= 3/13 </p><p>找到P（m）<1/12345的最小m </p></section>
