--description--

Given an array representing the weights of the athletes on a bobsled team and a number representing the weight of the bobsled, determine whether the team is eligible to race.

  • The length of the array determines the team size: 1, 2 or 4 person teams.
  • All given weight values are in kilograms (kg).

The bobsled (sled by itself) must have a minimum weight of:

  • 162 kg for a 1-person team
  • 170 kg for a 2-person team
  • 210 kg for a 4-person team

The total weight of the bobsled (athletes plus sled) must not exceed:

  • 247 kg for a 1-person team
  • 390 kg for a 2-person team
  • 630 kg for a 4-person team

Return "Eligible" if the team meets all the requirements, or "Not Eligible" if the team fails to meet one or more of the requirements.
