Answer:
Question is incomplete.
Assuming the below info to complete the question
You have a collection of n lockboxes and m gold keys. Each key unlocks at most one box. Without a matching key, the only way to open a box is to smash it with a hammer. Your baby brother has locked all your keys inside the boxes! Luckily, you know which keys (if any) are inside each box.
Detailed answer is written in explanation field.
Explanation:
We have to find the reachability using the directed graph G = (V, E)
In this V are boxes are considered to be non empty and it may contain key.
Edges E will have keys .
G will have directed edge b1b2 if in-case box b1 will have key to box b2 and box b1 contains one key in it.
Suppose if a key opens empty box or doesn’t contain useful key means can’t open anything , then it doesn’t belongs to any edge.
Now, If baby brother has chosen box B, then we have to estimate for other boxes reachability from B in Graph G.
If and only if all other boxes have directed path from box B then just by smashing box B we can get the key to box b1 till last box and we can unlock those.
After first search from B we can start marking all other vertex of graph G.
So algorithm will be O ( V +E ) = O (n+m) time.
Answer:
name and address of web visitors.
Explanation:
A website refers to the collective name used to describe series of web pages linked together with the same domain name.
Web analytical packages are software features that are typically used for tracking the identity of a computer system by placing or adding cookies to the computer when it's used to visit a particular website. Thus, it's only used for tracking the identity of a computer but not the computer users.
This ultimately implies that, web analytical packages can obtain the geographic location, Internet connection type, and navigation source information when someone visits a website, but it cannot obtain the name and address of web visitors or users.
Answer: Task manager
Explanation: The task manager window represents an interface in personal computers manufactures by Microsoft. The task manager window contains several information about a computers current processes usually displayed in graphical manner, in addition it provides information on the current running processes and application, the uptime of the computer, the graphic processor. With the task manager window users can set process priorities and prioritize applications, by affording users to view process and their corresponding load on the CPU, users can terminate or close applications from within the task manager interface. Hence non-responsuve programs can be viewed and terminated.
