Create a function that takes an array of hashes like { name=> "John", notes=> [3, 5, 4]} and returns an array of hashes like { name=> "John", avgNote=> 4 }. If student has no notes (an empty array) then avgNote is zero.

Examples

[
  { name=> "John", notes=> [3, 5, 4]}
] ➞ [
  { name=> "John", avgNote=> 4 }
]

Notes

Round the avgNote to a whole number.
