如何用此代码在左侧写章节号

我想要章节编号随着章节标题。 章节编号它应该位于左侧上方。

\documentclass{book}
\usepackage{tikz}
\usepackage{fourier}
\usepackage[explicit,calcwidth]{titlesec}
\usepackage{lipsum}

\definecolor{mybluei}{RGB}{0,173,239}
\definecolor{myblueii}{RGB}{63,200,244}
\definecolor{myblueiii}{RGB}{199,234,253}

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

\titleformat{\chapter}{}{}{0pt}{%
  \begin{tikzpicture}[remember picture,overlay]
  \fill[myblueiii]
    (current page.north west) rectangle ([yshift=-\titleheight]current page.north east);
  \node[
      fill=mybluei,
      text width=2\paperwidth,
      rounded corners=6cm,
      text height=1.5\titleheight,
      anchor=center,
      inner sep=0pt] at (current page.north east) (chaptop) {};
  \node[above left, inner xsep=0pt] at (chaptop.south)
    {\fontsize{90}{90}\color{white}\scshape\bfseries #1};
  \end{tikzpicture}%
  }

\begin{document}

\chapter{Problem}

\lipsum[1]
\section{Problem Statement 1}
\lipsum[1]

\chapter{Solution}
\section{Solution Statement 1}
\lipsum[1]
\section{Solution Statement 2}
\lipsum[1]

\appendix
\chapter{Appendix}
\lipsum[1]
\chapter{References}
\lipsum[1]
\end{document}

下面介绍了一个根据或\ifstarredchapter的使用而打开/关闭的条件。这允许人们放置适当的章节标签，而不需要其他麻烦\chapter*\chaptertitlesec内部。

带圆圈的章节编号使用的内容来自自定义带圆圈的数字。

元素内的注释\raisebox显示了在哪里调整标题和标题之间的间隙，以及字体（当前设置为\Huge）。
