Program: Write a Marie program as follows:
Given a numbers in memory, labelled V, reverse its sign.
For example, if V is 357, the result should be -357. If V is -12421, the result should be 12421.
(No I/O is required for this task. You can halt your program once the Result is determined.)
You need to make well-formed and clean code. You should not copy and paste the code from other source.
