Sliding window algorithms can be implemented with a single pointer and a variable for window size. Typically we use all of the elements within the window for the problem (for eg – sum of all elements in the window). Two pointer technique is quite similar but we usually compare the value at the two pointers … Read more
If the array elements are not guaranteed to be distinct, then it’s not possible to do this in O(log n) time. The reason for this is the following: suppose that you have an array where all n > 1 values are the same. In this case, none of the elements can be local minima, because … Read more
One way to translate an imperative for loop to Clojure is to use the for macro. (for [i (range 10)] (inc i)) The above function will return all the numbers from 0 to 9 incremented by 1. However, it appears you simply want to iterate over a sequential collection and use each item. If that’s … Read more
Iterators.flatten(x) creates a generator that iterates over each element of x. It can handle some of the cases you describe, eg julia> collect(Iterators.flatten([(1,2,3),[4,5],6])) 6-element Array{Any,1}: 1 2 3 4 5 6 If you have arrays of arrays of arrays and tuples, you should probably reconsider your data structure because it doesn’t sound type stable. However, … Read more
You can brute force it like this: Public Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean Dim i For i = LBound(arr) To UBound(arr) If arr(i) = stringToBeFound Then IsInArray = True Exit Function End If Next i IsInArray = False End Function Use like IsInArray(“example”, Array(“example”, “someother text”, “more things”, “and another”))
UPDATE: since Dart 3.0, package:collection is no longer required to use method firstOrNull. Thanks to @Mrb83 for pointing this out. Now you can import package:collection and use the extension method firstOrNull import ‘package:collection/collection.dart’; void main() { final myList = []; final firstElement = myList.firstOrNull; print(firstElement); // null }
I’m going on the assumption here that you only need to retrieve just the bare arrays, and not any associated model objects. This will do it: $model = Trips::model(); $trips = $model->getCommandBuilder() ->createFindCommand($model->tableSchema, $model->dbCriteria) ->queryAll(); This is like the Yii::app()->db->createCommand(‘SELECT * FROM tbl’)->queryAll(); examples, except: It’ll ask the model for the table name; you won’t … Read more
I finally managed to make it work with your help! Here’s my code: function do_upload() { $this->load->library(‘upload’); $files = $_FILES; $cpt = count($_FILES[‘userfile’][‘name’]); for($i=0; $i<$cpt; $i++) { $_FILES[‘userfile’][‘name’]= $files[‘userfile’][‘name’][$i]; $_FILES[‘userfile’][‘type’]= $files[‘userfile’][‘type’][$i]; $_FILES[‘userfile’][‘tmp_name’]= $files[‘userfile’][‘tmp_name’][$i]; $_FILES[‘userfile’][‘error’]= $files[‘userfile’][‘error’][$i]; $_FILES[‘userfile’][‘size’]= $files[‘userfile’][‘size’][$i]; $this->upload->initialize($this->set_upload_options()); $this->upload->do_upload(); } } private function set_upload_options() { //upload an image options $config = array(); $config[‘upload_path’] = ‘./Images/’; … Read more
If I understand your question correctly you have a string and you’re first splitting it on some separator and then afterwards finding the last element of the array and discarding the rest. You could miss out the middle man and get the last element directly: SELECT regexp_replace(‘foo bar baz’, ‘^.* ‘, ”) Result: baz
All your variables have a slice type. Slices have a backing array. In Go you can’t access uninitialized variables. If you don’t explicitly provide a value when you create a new variable, they will be initialized with the zero value of the variable’s type. This means when you create a slice with make([]int, 0, 5), … Read more
