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.
Output:
Output: 1111 112 121 13 211 22 31 4
