Complete a function that identifies the track with the highest energy level from a list of tracks. Each track is represented as a dictionary containing various fields, including an energy field that indicates the track's energy level.

Inputs:

• tracks: A list of dictionaries, where each dictionary represents a track and contains at least the following fields:
  • track_name: A string representing the name of the track.
  • energy: A float representing the energy level of the track.

Steps:

• Iterate Through Tracks:
  • Loop through each track in the tracks list.
  • For each track, compare its energy value with highest_energy.
  • If the track's energy is greater than highest_energy, update most_energetic_track with the current track's track_name and update highest_energy with the current track's energy.
