c++ programming, I need explain not just answer, thanks

Consider the following structure. struct Node ( Node "prev: int key Node "next, 10 12 Consider a pointer named head that points to the first node in the linked list, a pointer named tail that points to the last node. a pointer named temp that points to the node with value 7 and a node named newnoce with the value 15. After executing following code newmode->prev = temp temp-snextsprev newnode temp.snextnewnode; newnode. >next = tempnext what will be the output if we print the linked list from tail to head? Select one: o a. Segmentation tault O b 12 5 1073 O c. infinite loop d 12 5 15 1073 O e. none of these 1.37 10 15 5 12 Check

Explanation / Answer

ANSWER

Given code to obtain A) 12 5 10 7 3

Because we havde pointers at first and last nodes as from the code execution at frist step we have assigned it with last node to new node and next after that we have incremented to next prev that is value 5 node and then weith the help of the temp we have iterate it to up to next-prev is empty that is up to first node.

So the ouput of the code is 12 5 10 7 3
