const tupleFrom = (str) =>
  str.slice(2, -2).split('},{')
    .map((it) => toNumbers(it))
    .sort(accendingByLength)
    .reduce((acc, cur) =>
      [...acc, ...cur.filter((it) => !acc.includes(it))], []);

const toNumbers = (str) => str.split(',').map(it => Number(it));

const accendingByLength = (arr1, arr2) => arr1.length - arr2.length;

const solution = (s) => tupleFrom(s);

1. 성공 ⭕     

function solution(s) {
    var answer = [];
    let arr = s.replaceAll("{{","").replaceAll("}}","").split("},{")
    let arr2=[]
    arr.forEach((value)=>{
        arr2.push(value.split(","))
    })
    arr2.sort((a,b)=>{
        return a.length-b.length
    })

    arr2.forEach((value,index)=>{
        value.forEach((ele)=>{
            if(!answer.includes(Number(ele))){
                answer.push(Number(ele))
            }
        })
    })
    
    return answer;
}
