| * Lodash mixins for combinatorics | |
| * Inspired by python itertools: https://docs.python.org/2.7/library/itertools.html | |
| * | |
| * Usage: | |
| * permutations([0,1,2],2) // [[0,1],[0,2],[1,0],[1,2],[2,0],[2,1]] | |
| * combinations([0,1,2],2) // [[0,1],[0,2],[1,2]] | |
| * combinations_with_replacement([0,1,2],2)// [[0,0],[0,1],[0,2],[1,1],[1,2],[2,2]] | |
| * product([0,1,2],[0,1,2]) // [[0,0],[0,1],[0,2],[1,0],[1,1],[1,2],[2,0],[2,1],[2,2]] | |
