python program to figure out how many numbers there are between 1-x with repeating digits.
def get_digits(num):
rem = num % 10
it_num = num/10
digits = []
while(rem > 0 or it_num > 0):
if rem in digits: return None
digits.insert(0, rem)
rem = it_num % 10
it_num = it_num/10
return num

Created March 30, 2014 01:32
This is my implementation of the Levenshtein algorithm as described from Wikipedia (http://en.wikipedia.org/wiki/Levenshtein_distance). This was meant to test out the effectiveness of the algorithm.
'use strict';
// this function creates an M+1xN+1 matrix where M is the length of the first string
// and N is the length of the second string and computes the number of changes it would
// require to convert string s to string t. The value at point (i,j) is the cost to
// compute s from [0..i] to t from [0..j]
function levenshtein(s, t) {
var m = s.length + 1;
var n = t.length + 1;
function sudoku(puzzle) {
if (solved(puzzle)) {
return puzzle;
}
var copy = puzzle.slice(0);
for(var x=0;x<9; x++) {
for(var y=0;y<9;y++) {
if (puzzle[x][y] !== 0) continue;
var available = get_available(puzzle, x,y);
for(var i = 0; i < available.length;i++) {

Add a method to Array to zero all the elements.
Array.prototype.zeros = function() { return Array.apply(null, {length: this.length}).map(function(x){ return 0;}); };
