 ## Solutions
 
+**Solution 1: DFS**
+
+We first construct a graph $g$ based on $pid$ and $ppid$, where $g[i]$ represents all child processes of process $i$. Then, starting from the process $kill$, we perform depth-first search to obtain all killed processes.
+
+The time complexity is $O(n)$, and the space complexity is $O(n)$. Here, $n$ is the number of processes.
