Explanation:
its too old question bro I can't answer just for points
Answer:
Let L and R be the sub-trees underneath the root r.
If the height of L (where we consider height to be the maximum length of all root-leaf paths) is ∆ more than that of R, ∆ ≥ 0, then the length of the edge (r, R) is increased by ∆.
Then, we separately perform the same cycle over L and R.
Once more, by induction, argue that this greedy algorithm is efficient –
when it does not increase the length of (r, R) edge by ∆, then prove that the solution can be improved.
Solution:
Users of an access point share the transmission capacity of the access point. The throughput a user gets is called the bits per seconds.
Thus this is the required answer.
Answer:
Google uses automated programs called spiders or crawlers, just like most search engines, to help generate its search results.
