Answer:
B.O(n).
Explanation:
Since the time complexity of visiting a node is O(1) in iterative implementation.So the time complexity of visiting every single node in binary tree is O(n).We can use level order traversal of a binary tree using a queue.Which can visit every node in O(n) time.Level order traversal do it in a single loop without doing any extra traversal.
Answer:
IDP sensors can be complicated.An open-source software program called snort program.
Explanation:
Snort is an open-source network intrusion detection system (IDS) and prevention system. It is created in 1998 by Martin. Snort's open source network-based can perform analysis and packet logging on an Internet Protocol network.
The snort program can be used to detect probes or attacks. Snort configured three modes
sniffer
pocket logger
network intrusion detection.
Paint,calculator,camera,snipping tool,file,store,and photis
