Battle of the characters (Easy) 
Groups of characters decided to make a battle. Help them to figure out which group is more powerful. Create a function that will accept 2 variables and return the one who's stronger.
Rules: 
- Each character have its own power: 
A = 1, B = 2, ... Y = 25, Z = 26 - Only capital characters can and will participate a battle.
 - Only two groups to a fight.
 - Group whose total power (
A + B + C + ...) is bigger wins. - If the powers are equal, it's a tie.
 
Example 
battle_of_the_characters("ONE", "TWO"); // => "TWO"`
battle_of_the_characters("ONE", "NEO"); // => "Tie!"
battle_of_the_characters("ONE", "TWO"); // => "TWO"`
battle_of_the_characters("ONE", "NEO"); // => "Tie!"Solution

    return x if x_total > y_total else y if x_total < y_total else 'Tie!'
