### 5번만 실패

function solution(n, lost, reserve) {
var answer = 0;
var newArr = [];
var sortReserve = reserve.sort();
var sortLost = lost.sort();
answer = n - lost.length;

for(var i = 0; i < sortReserve.length; i++){
if(sortLost.includes(sortReserve[i])){
newArr.push(sortReserve[i])
sortLost.splice(sortLost.indexOf(sortReserve[i]), 1);
}else{
if(sortLost.includes(sortReserve[i]-1)){
newArr.push(sortReserve[i]-1);
sortLost.splice(sortLost.indexOf(sortReserve[i]-1), 1);
}else if(sortLost.includes(sortReserve[i]+1)){
newArr.push(sortReserve[i]+1);
sortLost.splice(sortLost.indexOf(sortReserve[i]+1), 1);
}
}
}
console.log(newArr);

return answer + newArr.length;
}

왜 실패하는 것인지 잘 모르겠습니다.
