164. Print All Possible Subsets with Sum equal to a given Number

Objective: Given a number N, Write an algorithm to print all possible subsets with Sum equal to N

Example:

N=4

1111
112
121
13
211
22
31
4

Approach:

This problem is quite similar to Print All Subsets of a given set.

  • Loop through i=1 to N.
  • Add i to the result and make a recursive call to (N-i).
  • Base case: when n becomes 0

See the code for better explanation and recursion tree.
