Data Structures and Algorithms The Complete Masterclass - Depth-first Search Complexity

What is the time complexity of DFS for preorder, inorder, and postorder traversals?

• O(log N)

• O(N)

• O(N^2)

• O(1)

In the worst-case scenario, what is the space complexity of DFS?

• O(log N)

• O(N)

• O(N^2)

• O(1)

What factor primarily influences the space complexity of DFS?

• Number of nodes

• O(1)

• O(N^2)

How can space complexity be managed when outputting results in DFS?

• By using hash maps

• By using linked lists

• By using print statements

• By using arrays
