5

Explanation 0

Given list is . The maximum score is , second maximum is . Hence, we print  as the runner-up score.

if __name__ == '__main__':

    n = int(input())

    arr = map(int, input().split())

arr =list(arr)

arr.sort(reverse = True)

arr =  [i for i in arr if i != max(arr)]

print(max(arr))

String Characteristics

String Characteristics:

• It is a reference type.
• It’s immutable( its state cannot be altered).
• It can contain nulls.
• It overloads the operator(==).

Different Ways for Creating a String:

• Create a string from a literal
• Create a string using concatenation
• Create a string using a constructor
• Create a string using a property or a method
• Create a string using formatting
