// LZW Compression Function
function lzw_encode(s) {
  // Initialize variables
  var dict = {};
  var data = (s + "").split("");
  var out = [];

  // Iterate through characters
  for (var i = 0; i < data.length; i++) {
    // Check for existing code
    if (!dict.hasOwnProperty(data[i])) {
      // Encode and update dictionary
      dict[data[i]] = out.length;
      out.push(data[i]);
    }
  }

  // Return encoded string
  return out;
}

// LZW Decompression Function
function lzw_decode(s) {
  // Initialize variables
  var dict = {};
  var data = (s + "").split("");
  var out = [];

  // Add first character to dictionary
  dict[""] = data[0];

  // Iterate through codes
  for (var i = 1; i < data.length; i++) {
    // Check dictionary for code

      // If code exists for previous character, append previous character to previous phrase
