Given a set of numbers: A $=\{1,3,5,2,8,7,9,4\}.$

Add each digit of your N$-$Number $($e$.$g$.$ N $00322012)$ to each element of A separately to

get your own final array B$.($ e$.$g$.$ B$=\{1,3,8,4,10,7,10,6\}=\{$B$1,$B$2,$B$3,$B$4,$B$5,$B$6,$B$7,$B$8\}.)$

a$)$ Your set B $=?$

b$)$ Use merge$-$sort to sort the array B$.$ Show each step.

c$)$ How many $$comparisons$$ are used in the algorithm above?

$2$ How do you build a linked list in C$++$ or Java? Provide an example that holds $5$ numbers.
