Hey @officialharshit1996
Use vector instead of string in set otherwise gives wrong ans when 2digit or bigger number is in ans
Also ordering may be different
say
we have start as 4 and 28 in two different sequences then the sequence starting with 4 should be printed first but since u took string the one with 28 will be printed first

Here updated your code by using vector
