Previous problems have challenged you to create an algorithm for an application involving particles precipitating in a solution.

See http://hpcuniversity.org/students/weeklyChallenge/72/ and the "Precipitate Algorithm Solution txt" file below.

Your task is to take this algorithm and identify data and task dependencies within it.

A data dependency is an area of the algorithm in which a step cannot occur until certain data is set. For example, step 1b of the randomizePositions function cannot occur until the random number is set.

A task dependency is an area of the algorithm in which a step cannot occur until another step occurs first. For example, step 3 of the tryMove function cannot occur before step 2 of the same function occurs.

List all data and task dependencies you can find in the algorithm.
