Create a function that takes an array of student hashes and returns an array of their top notes. If the student does not have notes then let's assume their top note is equal to 0.

Examples

get_student_top_notes([
  {
    id: 1,
    name: "Jacek",
    notes: [5, 3, 4, 2, 5, 5]
  },
  {
    id: 2,
    name: "Ewa",
    notes: [2, 3, 3, 3, 2, 5]
  },
  {
    id: 3,
    name: "Zygmunt",
    notes: [2, 2, 4, 4, 3, 3]
  }
]) ➞ [5, 5, 4]
