The Silver Medal

The Second Best

Finding the maximum is easy; finding the runner-up requires tracking two leaders simultaneously.

The Assignment

Your function receives an array scores.

1. Initialize first and second to a very small number (-Infinity).
2. Iterate through the array.
3. If current > first, update second = first and first = current.
4. Else if current > second and current != first, update second.
5. Print second. If no such number exists, print -1.
