我对此感到很困惑。在我的代码中，第 39 行完全是空白的，其他地方没有错误，所有内容都适合边距，但我仍然收到错误Overfull \hbox (34.204pt too wide) in paragraph。这与行上的内容无关，因为无论是否为空，错误始终是第 39 行。我在下面附上了我的代码，还有其他人遇到过这个问题吗？

\subsubsection*{Programming Task}
A program using the given algorithm to compute the partial quotients and convergents of a fraction $u/v$ is shown on page ??.
\begin{enumerate}
\item Taking $u = 112, v = 27$ gives partial quotients $a_n$ as 4,6,1,3 and convergents $p_n/q_n$ as $\frac{4}{1}, \frac{25}{6}, \frac{29}{7}, \frac{112}{27}$
\item Taking $u = 4803, v = 3395$ gives partial quotients 1,2,2,2,3,6 and 13 with convergents $\frac{1}{1}, \frac{3}{2}, \frac{7}{5}, \frac{17}{12}, \frac{58}{41}, \frac{365}{258}, \frac{4803}{3395}$
\item Taking $u = 276272, v = 72159$ gives partial quotients 3,1,4,1,5,9,2,6,5 and 3 with convergents $\frac{3}{1}, \frac{4}{1}, \frac{19}{5}, \frac{23}{6}, \frac{134}{35}, \frac{1229}{321}, \frac{2592}{677}, \frac{16781}{4383}, \frac{86497}{22592}, \frac{276272}{72159}$
\item Finally, if $u = 11683474147$ and $v = 863334886$ then the partial quotients are 13,1,1,7,11,1,2,5,2,3,1,1,9,1,2,12,9,5 and the convergents are $\frac{1}{1}$
