In its draft on Generating all \\(n\\) tuples, of The Art of Computer Programming, Knuth presents the following algorithm for the generation of $n$-tuples (<a href="#citeproc_bib_item_1">Knuth 2002</a>).

<pre id="hello-world-code" class="pseudocode">
    \begin{algorithm}
    \caption{Mixed-radix generation}
    \begin{algorithmic}
    \State \textbf{M1.} [Initialize.] Set $a_j \gets 0$ for $0 \leq j \leq n$, and set $m_0 \gets 2$.
    \State \textbf{M2.} [Visit.] Visit the \(n\)-tuple $(a_1, ..., a_n)$ (The program that wants to examine all $n$-tuples now does its thing.)
    \State \textbf{M3.} [Prepare to add one.] Set $j \gets n$.
    \State \textbf{M4.} [Carry if necessary.] If $a_j = m_j - 1$, set $a_j \gets 0$, $j \gets j - 1$ and repeat this step.
    \State \textbf{M5.} [Increase, unless done.] If $j = 0$, terminate the algorithm. Otherwise set $a_j \gets a_j + 1$ and go back to step M2.
    \end{algorithmic}
    \end{algorithm}
