js sort solution 완주하지 못한 선수
// https://programmers.co.kr/learn/courses/30/lessons/42576
function solution(p, c) {
var size = c.length;
// 이렇게 하면 오류 발생
// p.sort((a,b)=>(a < b));
// 이렇게 하면 속도 느림
// p.sort((a,b)=>(a.localeCompare(b)));
// 속도 제일 빠르고 정확함
p.sort((a,b)=>(a < b ? -1 : (a > b ? 1 : 0)));
c.sort((a,b)=>(a < b ? -1 : (a > b ? 1 : 0)));
