Given a string of words, you need to find the highest scoring word.
Each letter of a word scores points according to its position in the alphabet: `a = 1, b = 2, c = 3` etc.
You need to return the highest scoring word as a string.
If two words score the same, return the word that appears earliest in the original string.
All letters will be lowercase and all inputs will be valid.
def high(x):
    highest_score = 0
    for word in x.split(' '):
        score = sum(ord(c)-96 for c in word)
        if score > highest_score:
            highest_score = score
            highest_word = word
            
    return highest_word
def high(x):
    highest_score = 0
    for word in x.split(' '):
        score = sum(ord(c)-96 for c in word)
        if score > highest_score:
            highest_score = score
            highest_word = word
            
    return highest_word
