What is the fastest non-LINQ algorithm to 'pair up' matching items from multiple separate lists?

Tag : chash , By : Puneet Madaan

it should still fix some issue This didn't turn out as neat as I'd hoped, but if both input lists are sorted then you can just walk through them together comparing the head elements of each one: if they're equal then you have a pair, else emit the smallest one on its own and advance that list.
public static IEnumerable<ListPairing> PairUpLists(IEnumerable<int> sortedAList,
                                                   IEnumerable<int> sortedBList)
    // Should wrap these two in using() per Servy's comment with braces around
    // the rest of the method.
    var aEnum = sortedAList.GetEnumerator();
    var bEnum = sortedBList.GetEnumerator();
    bool haveA = aEnum.MoveNext();
    bool haveB = bEnum.MoveNext();

    while (haveA && haveB)
        // We still have values left on both lists.
        int comparison = aEnum.Current.CompareTo(bEnum.Current);
        if (comparison < 0)
            // The heads of the two remaining sequences do not match and A's is
            // lower. Generate a partial pair with the head of A and advance the
            // enumerator.
            yield return new ListPairing() {ASide = aEnum.Current};
            haveA = aEnum.MoveNext();
        else if (comparison == 0)
            // The heads of the two sequences match. Generate a pair.
            yield return new ListPairing() {
                    ASide = aEnum.Current,
                    BSide = bEnum.Current
            // Advance both enumerators
            haveA = aEnum.MoveNext();
            haveB = bEnum.MoveNext();
            // No match and B is the lowest. Generate a partial pair with B.
            yield return new ListPairing() {BSide = bEnum.Current};
            // and advance the enumerator
            haveB = bEnum.MoveNext();
    if (haveA)
        // We still have elements on list A but list B is exhausted.
            // Generate a partial pair for all remaining A elements.
            yield return new ListPairing() { ASide = aEnum.Current };
        } while (aEnum.MoveNext());
    else if (haveB)
        // List A is exhausted but we still have elements on list B.
            // Generate a partial pair for all remaining B elements.
            yield return new ListPairing() { BSide = bEnum.Current };
        } while (bEnum.MoveNext());

Use jQuery to find list items with matching class names in separate unordered lists

will be helpful for those in need I have two unordered lists, each filled with list items that have a DYNAMIC class name. When I say "dynamic" I mean they are not generated by me, but they don't change once the lists have been created. These class names are id's I'm getting from an API, so they're just random numbers. A simple example would be something like...
var $first  = $('ul.listA li'),
    $second = $('ul.listB li');

    var cls = this.className,
        $m  = $second.filter(function(){
            return this.className === cls;

    if ($m.length) {

       for (int i = 0; i < resultArray.count; i++) {

         Book *bookObj=[resultArray objectAtIndex:i];
        NSRange rangeValue1 = [test rangeOfString:searchText options:NSCaseInsensitiveSearch];

        if (rangeValue1.length != 0) {
