The who owes what problem

Hi all, this being my first post be gentle. Let me know if this doesn't make sense or I am over complicating the problem.

I have been struggling to get the output i want from a single formula and the problem goes as follows.

Total owed = 1 1 1 1 1 1 1 1 1 1 = 10

Person A = 1 1 2 0 2 1 2 1 0 1 = 11

Person B = 1 1 0 0 0 0 0 0 0 0 = 2


Person A owes the Total 2 (Because Person A is yet to pay 4th and 9th payment to the Total)
Person B owes the Total 8 (Because Person B is yet to pay 3rd to 10th payments to the Total)
Person B owes person A 2 (Because Person A payed for Person B twice)

The values payed by Person A and B are always half of each other (i.e Person B payed 100, Person A payed 0, so A owes B 50 and the Total 50) Ideally i would like 4 cell outputs:

Person A owes Total x amount
Person B owes Total x amount
Person A owes Person B x amount
Person B owes Person A x amount
