How proceed and mistakes i am doing......should i return vector

#1
#2

hi @neelrai906, there are some errors in your code :-

  1. you are doing if(a[i]==’\0’){ but integer arrays doesn’t end with ‘\0’ , you have to pass the length of array in the parameter for your base condition
  2. In your base condition you forgot to return .
  3. you forgot to take input of n.

I have corrected your code till your logic :- https://ide.codingblocks.com/s/265062
this code still misses the case on removing duplicates and ordering among subsets.

I want you to try to think by yourself.
hint:- you can use vector<vector > to store your answer and finally sort the vector<vector > to have ordered output .
2. you can use set or map to check for duplicates

you can refer to this code :- https://ide.codingblocks.com/s/265065
explanation is included in the code link

In case of any doubt feel free to ask :slight_smile:
