      @@itzzRaghav I think 2 can also be solved by starting from end in the permutation.
      if we fill the permutation array from the end we always know the mex is n initially we can find the last element of permutation and now if it is less than the curr mex update the mex and find the permutation again with the formula mex-an

      I think it's a fault with zoom, during live class the audio was fine.
