在引文中打印顶点/上标和下标

Question

我正在尝试在伪代码中打印顶点和下标。我使用此代码编写了它，但它按原样打印它，而没有进行数学转换。

\begin{quote}\linenumbersep=-5pt
\resetlinenumber[1]
\begin{alltt}{\internallinenumbers

FLOYD-WARSHALL(W):
     n = W.righe
     D\(^{(0)}\) = W
     for k = 1 to n:
          sia D\(^{(k)}\) = d\(_{ij}^{(k)}\) una nuova matrice n x n
          for i = 1 to n:
          for j = 1 to n:
               d\(_{ij}^{(k)}\) = min(d\(_{ij}^{(k-1)}\),d\(_{ik}^{(k-1)}\)+d\(_{kj}^{(k-1)}\) )
     return D\(^{(n)}\) 

}
\end{alltt}
\end{quote}

我该如何修复它，以便 $D^{(0)}$ 变成 D^(0)（因为我们用它来表示算法中的步骤，例如“在步骤 k 时为 D”）？谢谢

好的，您必须使用\(...\)数学模式、\sp和。^\sb_

\documentclass{article}

\usepackage{lineno,alltt}

          for i = 1 to n:
          for j = 1 to n:
               d\(\sb{ij}\sp{(k)}\) = min(d\(\sb{ij}\sp{(k-1)}\),d\(\sb{ik}\sp{(k-1)}\) + d\(\sb{kj}\sp{(k-1)}\))
     return D(n)

我添加了版本，algpseudocode并且我毫不怀疑我更喜欢哪一个。
