range

In C++, I have a std::set that I would like to insert a range of consecutive integers. How can I do this efficiently, hopefully in O(n) time where n is the length of the range? I'm thinking I'd use the inputIterator version of std::insert, but am unclear on how to build the input iterator. std::set<int> mySet; // Insert [34 - 75): mySet.insert(inputIteratorTo34, inputIteratorTo75); How can I create the input iterator and will this be O(n) on the range size? The efficient way of inserting already ordered elements into a set is to hint the library as to where the next element will be. For that

I have a data frame where one column contains a range (or ranges) of numbers. I would like to turn this into a list of numbers based of the given range. Example input: "35-40" or "35-43, 45-47" This should yield: [1] 35 36 37 38 39 40 and [1] 35 36 37 38 39 40 41 42 43 45 46 47 We can do a split and with Map , get the numbers do.call(Map, c(`:`, lapply(strsplit(df1$v1, '-'), as.numeric))) #[[1]] # [1] 35 36 37 38 39 40 41 42 43 44 45 #[[2]] #[1] 43 44 45 46 47 If we need to find the sequence within the string lapply(strsplit(df1$v1, "-"), function(x) Reduce(`:`, as.numeric(x))) #[1]] #[1] 35

I'm trying to set a range for a jquery datepicker that I have on my form but when I open the form it allows me to select any date. <input class="span2 datepicker" name="tw#local#changeRequest#DeliveryDate" type="text" id="dp1"> <!-- jQuery --> <script type="text/javascript" src="<#=tw.system.model.findManagedFileByPath('jquery-1.7.2.min.js', TWManagedFile.Types.Web).url;#>"></script> <!-- Datepicker Script --> <script type="text/javascript" src="<#=tw.system.model.findManagedFileByPath('bootstrap-datepicker_new.js', TWManagedFile.Types.Web).url;#>"></script> <script type="text/javascript"> $

I need to check if a string contains only characters from ranges: 'A'..'Z', 'a'..'z', '0'..'9' , so I wrote this function: function GetValueTrat(aValue: string): string; const number = [0 .. 9]; const letter = ['a' .. 'z', 'A' .. 'Z']; var i: Integer; begin for i := 1 to length(aValue) do begin if (not(StrToInt(aValue[i]) in number)) or (not(aValue[i] in letter)) then raise Exception.Create('Non valido'); end; Result := aValue.Trim; end; but if for example, aValue = 'Hello' the StrToInt function raise me an Exception. fantaghirocco An unique set of Char can be used for your purpose. function

I have the following code using a for loop: total = 0 for num in range(101): total = total + num print(total) Now the same result using a while loop: num = 0 total = 0 while num <= 99: num = num + 1 total = total + num print(total) Why is it that I do not have to define num in the first case, but I do have to define it in the second? Are they both not variables? I'd like to approach this question from a slightly different perspective. If we look at the official Python grammar specification , we can see that (approximately speaking), a while statement takes a test , while a for statement takes

I currently have two arrays each of which contain ranges. How would you go about getting the intersection of these two arrays. In other words, I would like to get an array of ranges that only contains the ranges that are contained in both of the two original arrays. I tried .Intersect but that does not work on arrays as I learned. array1: (Range("A1"),Range("B1"),Range("C1")) array2: (Range("A1"),Range("A2"), Range("A3")) Result: (Range("A1")) you can use this code. The idea is to merge your array in a single range using an iterative Union . Then you can use the built-in Intersect . Function

Hy, I have a very Basic Question which is : How can i create a random number with 20 digits no floats no negatives (basically an Int) in Swift ? Thanks for all answers XD Here is some pseudocode that should do what you want. generateRandomNumber(20) func generateRandomNumber(int numDigits){ var place = 1 var finalNumber = 0; for(int i = 0; i < numDigits; i++){ place *= 10 var randomNumber = arc4random_uniform(10) finalNumber += randomNumber * place } return finalNumber } Its pretty simple. You generate 20 random numbers, and multiply them by the respective tens, hundredths, thousands... place

How can I create a apache commons 3.1 Range object? The java docs say: " An immutable range of objects from a minimum to maximum point inclusive. " " The objects need to either be implementations of Comparable or you need to supply a Comparator. " But when I try: Range<Integer> range = new Range<Integer>(100, 200); I get an error in my IDE that says required arguments are Integer, Integer, comparator. Even though Integer implements the Comparable interface and thus I shouldn't need a extra comparator. Can someone give me an example of how to construct a apache commons 3.1 Range object? The

I can't seem to find anything on google about this. I know you can pretty much rule out IE. I know webkit supports it but what else do you know? deceze At the time of writing, apparently (Desktop) Safari, Chrome and Opera support range inputs, according to Dive Into HTML5 . Ok, this question has been here quite a while, but I wanted to add this anyway. Regarding a question about browser support, a good source is always the caniuse.com website. In this case, you can find the current, past and expected future support for the range input here: http://caniuse.com/#feat=input-range 来源： https:/
