 <p>We can use a hash table $\textit{d}$ to store each element and its corresponding index.</p>
 <p>Traverse the array $\textit{nums}$, for the current element $\textit{nums}[i]$, we first check if $\textit{target} - \textit{nums}[i]$ is in the hash table $\textit{d}$. If it is in $\textit{d}$, it means the $\textit{target}$ value has been found, and we return the indices of $\textit{target} - \textit{nums}[i]$ and $i$.</p>
 <p>Time complexity is $O(n)$, and space complexity is $O(n)$, where $n$ is the length of the array $\textit{nums}$.</p>
