按一定顺序添加数字

Question

我尝试按照如下所示的特定顺序添加一些数字，但没有成功，有什么想法吗？

我的代码：

\documentclass{article}

\usepackage{graphicx}

\begin{document}

\begin{figure*}
     \centering
     \subfloat[]{\includegraphics[width =\linewidth]{a.PNG}}
     \subfloat[]{\includegraphics[width =\linewidth]{b.PNG}}
     \subfloat[]{\includegraphics[width =\linewidth]{c.png}}
     \subfloat[]{\includegraphics[width =\linewidth]{d.png}}
     \subfloat[]{\includegraphics[width =\linewidth]{e.png}}
    \caption{main caption}
     \label{f1}
    \end{figure*}

\end{document}

这是一个解决方案

\documentclass{article}
\usepackage{subfig}
\usepackage{graphicx}
\begin{document}
\begin{figure*}
 \centering
 \subfloat[]{\includegraphics[width =\linewidth]{example-image}}

 \subfloat[]{\includegraphics[width =\linewidth]{example-image}}

 \subfloat[]{\includegraphics[width =.3\linewidth]{example-image}}
 \subfloat[]{\includegraphics[width =.3\linewidth]{example-image}}
 \subfloat[]{\includegraphics[width =.3\linewidth]{example-image}}
\caption{main caption}
 \label{f1}
\end{figure*} 

\end{document}
