battle.js

// Description:
// 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 strings and return the one who's stronger.

// Rules:
// Each character have its own power: A = 1, B = 2, ... Y = 25, Z = 26
// Strings will consist of uppercase letters only
// 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.
