def find_second_largest(arr):
    if len(arr) < 2:
        print("Array should have at least two elements.")
        return

    largest = second_largest = float('-inf')

    for num in arr:
        if num > largest:
            second_largest = largest
            largest = num
        elif largest > num > second_largest:
            second_largest = num

    return second_largest

# Example usage:
