Subset Sum Algorithm

Implements the Subset Sum Problem using recursive backtracking. Implementation is provided as SubsetSum class contained in the package io.gitbub.thehappybug.Algorithms.

Compiling

The project can be compiled using make tool:

$ make
javac io/github/thehappybug/Algorithms/SubsetSum.java

Running

Run the class SubsetSum's main method using:

$ java io.github.thehappybug.Algorithms.SubsetSum
[-7, -3, -2, -1, 5, 8]
[-7, -3, 10]
[-7, -2, -1, 10]
[-7, -2, 9]
[-7, -1, 8]
[-3, -2, 5]

The program requires no arguments.
