    set<int> s;

    sort(arr.begin(), arr.end());
    sort(brr.begin(), brr.end());

    set_difference(brr.cbegin(),brr.cend(), arr.cbegin(),arr.cend(), inserter(s, s.begin()));
    
    return vector<int>(s.cbegin(), s.cend());

    Typescript

    function missingNumbers(arr: number[], brr: number[]): number[] {
    arr.sort((a, b) => a - b);
    brr.sort((a, b) => a - b);

  let set = new Set();
  let counter = 0;

  for (let i = 0; i < brr.length; i++) {
    if (arr[counter] !== brr[i]) {
      set.add(brr[i]);
      continue;
    }
    counter++;
  }

  return Array.from(set.values()) as number[];

}
