I can't get what do you need, but I guess it's a part of java code. I can explain what it means. It's used to unite two rising sorted arrays which are list1 and list2. The result is stored in result array. I suggest you to clearly explain your task as it's difficult to give you correct answer.
        
             
        
        
        
Answer:
 Redundant paths can be available without causing logical Layer 2 loops.
Explanation:
- Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops. 
- These loops are called physical loops. 
- When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop. 
- This affects the performance of the network as the result of broadcast packets flooding. 
- STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.
- Spanning Tree Algorithm is used by STP to determine the optimal path  of switch to the network.
- Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
- This information helps STP to eliminate the redundant paths.
- So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.
 
        
             
        
        
        
Generally I'd recommend not buying one online, tends to be cheaper from a shop - and better used, although their are some risks with 2nd hand devices, I think the big price cut it worth it. 
If you did want to buy online, maybe Amazon or Ebay?
