Knowledge, and your brain.
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:
Option D (External influences) is the correct choice.
Explanation:
- External factors including certain regulatory changes, the economy, globalization as well as new technologies may determine the effectiveness of such smaller businesses.
- They are the be the variables that may be out of a corporation's influence. While a company has no power regarding external factors, these factors may have a direct effect on the company.
Other given choices are not related to the given circumstances. So that option D would be the right one.
Applying potential difference to a conductor, by potential force, free electrons gain energy and move from low to high potential. Thus, electrons move from one atom to another.
