Explanation:
- The argument “x” is either in “%xmm0” or in named portion of register “%rdi”.
- The assembly instructions are used to perform type conversion and to copy value to named portion of register “%rax”...

The union of two ordered lists (Sequential linear list)[the solution
introduction: The first video of in 3.1, 35:00-43:00]
[Problem description]
Give the union of two ordered lists. The maximal number of elements in an
inputted set is 30.
[Basic requirements]
1) Use sequential linear list.
2) The result list should also be ordered.
[Example]
Problem: Give the union of the ordered lists (3,4,9,100,103) and
(7,9,43,53,102,105).
What you need to show in the terminal(the back part is outputted by you
and the blue part is inputted by the user, i.e., teacher):
Please input the first ordered list: (3,4,9,100,103)Please input the second ordered list: (7,9,43,53,102,105)
The union is:
(3,4,7,9,9,43,53,100,102,103,105)
(4) [8]Write code for a function multBy3divBy4, that for argument int x, computes 3*x/4, but follows the bit-level integer coding rules (text p.128) like in problem 3 of the assignment 1. (you may assume ints are 32 bits).
(Note: The operation in your code 3*x is allowed to cause overflow.)
