修改花式章节标题以显示章节名称

Question

在下面给出的代码中，我希望显示章节名称，而不是仅显示前两章的数字。此代码是根据找到的代码构建的这里。

我正在为第 1 章编写“问题”，为第 2 章编写“解决方案”。因此，我希望“问题”出现在章节标题上，第一章的数字为 1，然后“解决方案”出现在第二章的数字为 2 的位置。对于表格列表、图表列表等，以及附录中的所有其他章节，我希望保留标题的当前状态。您能帮我修改代码，以便只有前两章显示名称而不是数字，例如第 1 章：

以下是代码：

Answer 1

章节文本的起始点似乎固定在文本区域顶部下方约 4 厘米处。我根据个人喜好进行了调整\fontsize，1.5\titleheight因此您也可以随意调整它们。

注意：通过创建一个具有圆角的盒子来实现弯曲的形状，该盒子只有左下象限在纸上。

\newlength{\titleheight}
\setlength{\titleheight}{\dimexpr 1in+\topmargin+\headheight+\headsep+4cm}

\titleformat{\chapter}{}{}{0pt}{%
