Find The Runner - Up Score! in Python - Hacker Rank Solution

Hey, What's up Coders. Coding is fun for many people, but sometimes it becomes a burden to coders if they get a simple error in their code. To get rid of such minor errors one should practice coding on different platform like HackerRank, CodeChef and Codeforces etc. 

So, today we are going to solve one of the hackerrank problems of python. After reading this post you will find the solution very simple, and you yourself will be able to solve the problem very easily.

Problem

Given the participants' score sheet for your University Sports Day, you are required to find the runner-up score. You are given n scores. Store them in a list and find the score of the runner-up.

Input Format

The first line contains n. The second line contains an array A[] of n integers each separated by a space.

Constrains

• 2 ≤  n ≤  10
• -100 ≤  A[i] ≤ 100

Output Format

Print the runner-up score.

Sample Input 0

5
2 3 6 6 5

Sample Output 0

5

Explanation 0

Given list is [2, 3, 6, 6, 5]. The maximum score is 6, second maximum score is 5. Hence, we print 5 as the runner-up score.

Python 3

if __name__ == '__main__':
    n = int(input())
    arr = map(int, input().split())
    print(sorted(list(set(arr)))[-2])

Find The Runner - Up Score - Python

Solution Result

Explanation

Here in the source code we have used if __name__ == '__main__. Whenever python interpreter reads and source file, it sets a few special variables like __name__. It basically allows the code in module to importable by other modules without executing the code.

The second line of our code is quite simple. Most of you are aware of it, it is use to take the input from the user. 

Split is use to covert a string into array of sub strings and return the new array.
