#38  Highest Scoring Word

Given a string of words, you need to find the highest scoring word.

Each letter of a word scores points according to it's 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.

import java.util.Arrays;

public class HighestScoringWord {
	
	  private final static String ALPHABET = "abcdefghijklmnopqrstuvwxyz";
	  
	  public static String high(String s)  {
		  int high = Integer.MIN_VALUE;
		  String result = "";
		  for (String item : s.split(" ")) {
			  int sum = Arrays.stream(item.split("")).mapToInt(x -> ALPHABET.indexOf(x)+1).sum();
			  if(high < sum) {
				  high = sum;
				  result = item;
			  }
		  }
		  return result;
	  }

}

import java.util.*;

public class Kata {
  public static String high(String s) {
    return Arrays.stream(s.split(" "))
                .max(Comparator.comparingInt(
                        a -> a.chars().map(i -> i - 96).sum()
                )).get(); 
  }
