Sum it up question

#1

Hello @Chitra_Singla,

Your code will fail for the cases when there two recursion paths leads to the same set of numbers due to the duplicate numbers in the input set of elements.
Example:
7
10 1 2 7 6 1 5
8
Expected Output:
1 1 6
1 2 5
1 7
2 6
Your Output:
1 1 6
1 2 5
1 7
1 2 5
1 7
2 6

Hope, this would help.
Give a like if you are satisfied.

Sure @Chitra_Singla,

You can use set to remove duplicates.
