//Week-4 Exercise 15 Highest Score
/*
Implementasikan function highestScore untuk mendapatkan student dengan nilai tertinggi dari setiap class:
Output yang diharapkan berupa Object Literal dengan format sebagai berikut:

{
  <class>: { name: <name>, score: <score> },
  <class>: { name: <name>, score: <score> },
  <class>: { name: <name>, score: <score> }
}
