You can use Gson but you need to add Gson to your dependencies. Parse array to a string, store it in database as a string and convert it back to double 2D array when you need the array. Gson gson = new GsonBuilder().create(); double[][] multiDoubleArray = new double[][]{{1.0, 2.0, 3.0}, {4.0, 5.0, 6.0}}; // to … Read more
To hopefully help you with server timestamp I have modified the simple react-firebase-hook app created as an answer for this question: https://stackoverflow.com/a/60504303/610053 I’ve updated my Firebase class with an extra method called serverTimestamp: class Firebase { constructor() { app.initializeApp(firebaseConfig); this.realtimedb = app.database(); this.firestore = app.firestore(); this.serverTimestamp = app.firestore.FieldValue.serverTimestamp; } } const FirebaseContext = React.createContext(null); const … Read more
This will add a numbered (name, job) pair for each name: dict = {} i = 0 # or 1, if you prefer. but it’s not proper to start a list from 1 when programming. while i < len(names): dict[i] = (names[i], Jobs[i]) i = i+1 as a for loop: for i in id_: dict[i] … Read more
Here you use the correct way of formatting the path in Windows with a Backslash ofd.InitialDirectory = @”C:\Picture”; And in the next line you divert from it System.IO.File.Copy(ofd.FileName, “/Resources/SImages/” + lblRNo.Text + “.jpg”); just keep the way you did it in the beginning: System.IO.File.Copy(ofd.FileName, @”\Resources\SImages\” + lblRNo.Text + “.jpg”); One way of avoiding such irritations … Read more
Right now, the else clause fires if there is a at least one key that does not match vehicle. Fix it like this: def add_to_dict(product_type, brand, product_dict): if product_type in product_dict: product_dict[product_type].append(brand) else: product_dict[product_type] = [brand] product_dict = {} add_to_dict(“car”, “audi”, product_dict) add_to_dict(“car”, “mercedes”, product_dict) add_to_dict(“phone”, “apple”, product_dict) print(product_dict) # Output: # {“car”: [“audi”,”mercedes”], “phone”: … Read more

You only need to have the button click add the class membership, wait until the animation is complete and then remove the class. var div = document.querySelector(“.fade”); var btn = document.querySelector(“.fadeButton”); btn.addEventListener(“click”, function(){ div.classList.add(“elementToFadeInAndOut”); // Wait until the animation is over and then remove the class, so that // the next click can re-add it. … Read more
In more layman’s terms, it means that for each record in Table A, you get every record from Table B (all possible combinations). TableA with 3 records and Table B with 3 records gives 9 total records in the result: TableA-1/B-1 TableA-1/B-2 TableA-1/B-3 TableA-2/B-1 TableA-2/B-2 TableA-2/B-3 TableA-3/B-1 TableA-3/B-2 TableA-3/B-3 Often used as a basis for … Read more
The Java compiler thinks that it is possible that loops won’t execute (For example it nums[0] is bigger than the length) . In that case your method won’t call a return. So you have to put a return at the end. public int[] twoSum(int[] nums, int target) { for(int i=nums[0];i<nums.length;i++){ for(int x:nums){ if (x!=i & … Read more
The localtime function is not thread-safe and more importantly not reentrant. The pointer it return is most likely a pointer to an internal static buffer. This means that each localtime call returns the very same pointer to the very same “buffer” (structure). In fact, if you read the linked reference, the buffer (structure) can be … Read more

I think the best idea is to use a data-[type] and compare it with an ID, class or other data-type. You can also do this with a class ofcourse. Here is a fiddle. And here is the jQuery code: $(“div#links > a”).hover( function() { var ID = $(this).data(“content”); $(“div#images”).children(“img#” + ID).fadeIn(“slow”); }, function() { var … Read more
Use CSS 3 selector to apply your style, in this case I used the :nth-of-type(n)selector, which matches every element that is the nth child, of a particular type, of its parent. Using :nth-of-type(n) you do not need to introduce any additional hidden class. Use display:none to hide an element, it will not be available in … Read more
