}

right = {
    "m": 4,
    "q": 3,

    "z": 1,
}

def alphabet_war(fight):
    left_point = sum(left.get(i, 0) for i in fight)
    right_point = sum(right.get(i, 0) for i in fight)

    result = {
        left_point > right_point: "Left side wins!",
        left_point < right_point: "Right side wins!",
        left_point == right_point: "Let's fight again!"
