This function will find all the absolute numbers that are in both the negative and positive parts of a vector and put those numbers into merge_v.

If s is: //-43 -41 -40 -39 -37 -37 -31 -23 -21 -18 -17 -7 -3 41 39 12 12 7 7 5

//then merge_v would be //41 39 7.

// Input v with all the negative numbers are on the left, and the positive number are on the right.

Mid is the position of the last negative number or the position of the first positive number

// Output merge_v an ordered list of the absolute numbers in v that are in both the negative and positive parts.
