Game of Thrones - I

    Merge odd and even situations. That means regardless the len(str) is odd or even, just when the count of each elements have no more than ONE, the str is palindrome.

    from collections import Counter
def gameOfThrones(s):
    # Complete this function
    num_odd = 0
    s1 = Counter(s)
    for each in s1.values():
        if each % 2 != 0:
            num_odd += 1
            # when num_odd > 1, not palindrome
            if num_odd > 1:
                return 'NO'
    return ('YES')
