Game Rules

Both players have to make substrings using the letters of the string .
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 +1 point for each occurrence of the substring in the string .

For Example:
String  = BANANA
Kevin’s vowel beginning word = ANA

Problem solution in Python 2 programming.
# Enter your code here. Read input from STDIN. Print output to STDOUT
vowels = ['A', 'E', 'I', 'O', 'U']
s = raw_input()
a = 0
b = 0
for i, c in enumerate(s):
    if c in vowels:
        b += len(s) - i
    else:
        a += len(s) - i
        
if a == b:
    print "Draw"
elif a > b:
    print 'Stuart {}'.format(a)
else:
    print 'Kevin {}'.format(b)

def minion_game(string):
    vowels = 'AEIOU'
    Stuart_score, Kevin_score = 0, 0
    length = len(string)
    for start_idx in range(length):
        score = length - start_idx
        if string[start_idx] in vowels:
            Kevin_score += score
        else:
            Stuart_score += score
    if Stuart_score == Kevin_score:
        print('Draw')
    if Stuart_score > Kevin_score:
        print('Stuart {}'.format(Stuart_score))
    if Stuart_score < Kevin_score:
        print('Kevin {}'.format(Kevin_score))
