## Description

|
|
<section id="description">一排五个黑色正方形瓷砖是用彩色椭圆形瓷砖代替的，其中红色（长度为2），绿色（长度为3）或蓝色（长度为4）。如果选择红色瓷砖，则可以通过七种方式完成此操作。 <p>如果选择绿色瓷砖，有三种方法。 </p><p>如果选择蓝色瓷砖，有两种方法。 </p><p>假设颜色不能混合，则有7 + 3 + 2 = 12种方式替换长度为五个单位的行中的黑色瓷砖。如果不能混合颜色并且必须使用至少一个彩色瓷砖，那么连续测量五十个单位的黑色瓷砖有多少种不同的方式可以替换？注意：这与问题117有关。 </p></section>
