DESCRIPTION:

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.

For example, the score of abad is 8 (1 + 2 + 1 + 4).

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.

 

코드

function high(x){
  x = x.split(' ');
  let max = 0;
  let maxIndex = 0;
  for(let i = 0; i < x.length; i++){
    let sum = 0;
    for(let j = 0; j < x[i].length; j++){
      sum += x[i].charCodeAt(j) - 96;
    }
    if(sum > max){
      max = sum;
      maxIndex = i;
    }
  }
  return x[maxIndex];
}
