Dancing Links Implementation

An implementation of Donald Knuth's Dancing Links Algorithm to solve exact cover problems.

var dlx = require('dancing');
var matrix = [
  [1, 0, 0, 1, 0, 0, 1],
  [1, 0, 0, 1, 0, 0, 0],
  [0, 0, 0, 1, 1, 0, 1],
  [0, 0, 1, 0, 1, 1, 0],
  [0, 1, 1, 0, 0, 1, 1],
  [0, 1, 0, 0, 0, 0, 1]
];
dlx.solve(matrix); //=> [[1, 3, 5]]
