- Ans.
The question asks to construct a k-ary tree using the given k and DFS traversal string.
Iterate through the DFS traversal string
If the current character is 'P', create a parent node
If the current character is 'L', create a leaf node
Link the nodes according to the DFS traversal order
- Q2. "How would you tell whether a graph has a node with n degree?"
- Ans.
To determine if a graph has a node with n degree, iterate through all nodes and count their edges.
Iterate through each node in the graph
Count the number of edges connected to each node
If any node has n edges, then the graph has a node with n degree
