HackerRank Python Solution - Strings - The Minion Game

• Kevin and Stuart want to play 'The Minion Game'.

Game Rules:

• Both players are given the same string, S.
• Both players have to make substrings using the letters of the string S.
• Stuart has to make words starting with consonants.
• Kevin has to make words starting with vowels.
• The game ends when both players have made all possible substrings.

Scoring:

• A player gets a +1 point for each occurrence of the substring in the string S.

For Example:

• String S = BANANA
• Kevin's vowel beginning word = ANA
• Here, ANA occurs twice in BANANA. Hence, Kevin will get 2 Points.
• For a better understanding, see the image below:

• Your task is to determine the winner of the game and their score.

Function Description:

• Complete the minion_game in the editor below.
• minion_game has the following parameters:
• string: the string to analyze
• Prints string: the winner's name and score, separated by a space on one line, or Draw if there is no winner

Input Format:

• A single line of input containing the string S.
• Note: The string S will contain only uppercase letters: [A-Z].

Constraints:

• 0 < len(S) <= 10⁶

Sample Input:

BANANA

Sample Output:

Stuart 12

Note: Vowels are only defined as AEIOU. In this problem, Y is not considered a vowel.

Solution:

def minion_game(string):
    kevin_score = 0
    stuart_score = 0
    vowels ='AEIOU'
    
    for i in range(len(string)):
        if string[i] in vowels: 
            kevin_score += (len(string)-i)
        else:
            stuart_score += (len(string)-i)
    
    if kevin_score > stuart_score:
        print("Kevin",kevin_score)
    elif kevin_score < stuart_score:
        print("Stuart",stuart_score)
    else:
        print("Draw")

if __name__ == '__main__':
    s = input()
    minion_game(s)
