sorted

I have a similar question to this question: Determine if 2 lists have the same elements, regardless of order? What is the best/quickest way to determine whether an unsorted list list1 is contained in a 'list of lists' myListOfLists , regardless of the order to the elements in list1 ? My attempt is wrapped up in the function doSomething(...) which I call many times: def doSomething(myListOfLists, otherInputs): list1 = [] ... # do something here with `otherInputs' ... # which gives `list1' some values # now only append `list1' to `myListOfLists' if it doesn't already exist # and if it does exist

When you call sorted(<#source: C#>, <#isOrderedBefore: (C.Generator.Element, C.Generator.Element) -> Bool##(C.Generator.Element, C.Generator.Element) -> Bool#>) you can access the two source elements for comparison via $0 and $1 . But how can I determine the index from where they were taken from the source? You could pass into sorted not a collection of elements, but the indices of the elements: let a = ["hello","i","must","be","going"] let idxs = sorted(indices(a)) { a[$0] < a[$1] } // produces [3, 4, 0, 1, 2] Or, if you don't like capturing a and wanted the elements themselves passed into

So I have this list, we'll call it listA. I'm trying to get the [3] item in each list e.g. ['5.01','5.88','2.10','9.45','17.58','2.76'] in sorted order. So the end result would start the entire list over again with Santa at the top. Does that make any sense? [['John Doe', u'25.78', u'20.77', '5.01'], ['Jane Doe', u'21.08', u'15.20', '5.88'], ['James Bond', u'20.57', u'18.47', '2.10'], ['Michael Jordan', u'28.50', u'19.05', '9.45'], ['Santa', u'31.13', u'13.55', '17.58'], ['Easter Bunny', u'17.20', u'14.44', '2.76']] If you want to return the complete list in sorted order, this may work.

Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. Example: Input: [ 1->4->5, 1->3->4, 2->6 ] Output: 1->1->2->3->4->4->5->6直接复用归并排序即可 /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solution { public: ListNode* mergeKLists(vector<ListNode*>& lists) { ListNode *res=NULL; for(int i=0;i<lists.size();++i) { if(NULL==res) { res=lists[i]; continue; } res=merge(res,lists[i]); } return res; } ListNode* merge(ListNode *l1,ListNode *l2) { if(NULL==l1)return

I am having real trouble with using stream and sorted to sort my ArrayList and hope someone can help out. The code uses Croatian words, but I don't think that will be a problem for someone who understands what I mean. This is the ArrayList ArrayList<Publikacija> listaPublikacija = new ArrayList<>(); listaPublikacija.add(prvaKnjiga); listaPublikacija.add(drugaKnjiga); listaPublikacija.add(prviCasopis); listaPublikacija.add(drugiCasopis); In my assignment I am supposed to sort these objects above by getCijena() which is double. This is the best I got and it still doesn't sort it as it should...
