You will need to:

  1. Create a full, detailed specification of the problem
  2. Design an algorithm to match the spec
  3. Code up the algorithm
  4. Test the code

If the tests fail you then need to ascertain whether your algorithm is flawed or just the implementation of it and then revisit steps 2 or 3 iteratively until all the tests pass.

Since your statement of the problem is woolly you probably need to start right at point 1. After that someone here might be able to help you with the other parts but only you know the initial problem to be solved.
