apply method

int apply(String s1, String s2, Applicable ratio)

Implementation

int apply(String s1, String s2, Applicable ratio) {
  var tokens1 = s1.split(RegExp('\\s+')).toSet();
  var tokens2 = s2.split(RegExp('\\s+')).toSet();

  tokens1.length;

  var intersection = tokens1.intersection(tokens2);
  var diff1to2 = tokens1.difference(tokens2);
  var diff2to1 = tokens2.difference(tokens1);

  var sortedInter = (intersection.toList()..sort()).join(' ').trim();
  var sorted1to2 =
      ('$sortedInter ${(diff1to2.toList()..sort()).join(' ')}').trim();
  var sorted2to1 =
      ('$sortedInter ${(diff2to1.toList()..sort()).join(' ')}').trim();

  var results = <int>[];

  results.add(ratio.apply(sortedInter, sorted1to2));
  results.add(ratio.apply(sortedInter, sorted2to1));
  results.add(ratio.apply(sorted1to2, sorted2to1));

  return results.reduce(max);
