how to remove the duplicate sets .

#2

@shudhanshu20092001_af6f20d24c617008 Use this Approach :

  • Sort the array(non-decreasing).
  • First remove all the duplicates from array.
  • Then use recursion and backtracking to solve the problem.
      1. If at any time sub-problem sum == 0 then add that array to the result (vector of vectors).
      1. Else if sum if negative then ignore that sub-problem.
      1. Else insert the present array in that index to the current vector and call the function with sum = sum-ar[index] and index = index, then pop that element from current index (backtrack) and call the function with sum = sum and index = index+1
