In this HackerRank Find the Runner Up Score problem we need to develop a python program that can take an integer and array of values as an input and from the array we need to print the second-highest number. 



Problem solution in Python 2 programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT


def max(l):
    return sorted(set(l))[-2]

test = int(raw_input())
l = [int(_) for _ in raw_input().split()]
print max(l)


Problem solution in Python 3 programming.

if __name__ == '__main__':
    n = int(input())
    arr = map(int, input().split())
    arr = list(arr)
    x = max(arr)
    y = -9999999
    for i in range(0,n):
        if arr[i]<x and arr[i] > y:
            y = arr[i]
    
    print(y)


Problem solution in pypy programming.

if __name__ == '__main__':
    n = int(raw_input())
    arr = map(int, raw_input().split())
    Max = max(arr)
    while max(arr) == Max:
        arr.remove(max(arr))
    print max(arr)
