If you mean number in a matrix as follows (example for matrixSize == 4): 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 you can just calculate indexes from number matrixValues[number/matrixSize][number%matrixSize] EDIT: For case when your 2D arreay defined as int matrixValues[matrixSize][matrixSize]; All elements allocated in memory sequentially, … Read more
Okay, after so much discussion and so many issues with your code I have totally revised your original code because you said you wanted to learn more. Among other improvements I have done the following changes: Meaninfgul class name Meaningful method and parameter names Convert repeated and often used constants like 50 and the array … Read more
you have 2 variants Get a root object Root root = JsonConvert.DeserializeObject<Root>(jsonString); Get a list List<Set1> Set1 = JObject.Parse(jsonString)[“Set1”].ToObject<List<Set1>>(); solved not able to convert json string into c# object , getting error- because the type requires a JSON array
Recursion doesn’t seem to be necessary for the “parent” direct values, so that can be done with a direct foreach loop. The “children” indirect values require recursion. I’ve elected to use array_walk_recursive() to access every “leaf node” in the array. This will also store the parents’ indirect values too, so I subtract those values after … Read more
fmt.Println, won’t be showing “,” between each element of array if you want to print it that way you need to format and print it var datas [][]string json.Unmarshal(reqBody, &datas) fmt.Println(“this is after the unmarshalling”) array := []string{} for _, data := range datas { array = append(array, fmt.Sprintf(“[%s]”, strings.Join(data, “,”))) } output := fmt.Sprintf(“[%s]”, … Read more
For each code, you want to map an object. Array.prototype.map is perfect for this kind of treatment. const codes = [‘5′, ’13’, ’16’, ’22’, ’24’]; const mappedObjects = codes.map(code => { return { ‘0’: Number(code), ‘1’: ‘FFFRRR’, tx: 0, ty: 0, tz: 0, rx: 0, ry: 0, rz: 0, }; }); 4 solved Convert each … Read more
The second argument of the reduce function is the initial value, so for the sum it starts at 0. That’s why the ,0) is there for. 0 solved For what 0 between comma and bracket is used for?
This question does not really belong here, but I’ll answer it for the sake of closing the question without bothering moderators. // mysql query is executed $images = mysql_query(“Select URL from images where Category = ‘Management’ “); // empty array initialized $imagerow = Array(); // while there are results of the executed mysql query while … Read more
First, your JSON is wrongly formatted and it wouldn’t even parse. Assuming the JSON object is like this: “Categories”: { “cat1”: [ { “id”: 1, “Category_name”: “cat1”, “Name”: “iphone6”, “Details”: “packed”, } ], “cat2”: [ { “id”: 2, “Category_name”: “cat2”, “Name”: “GalaxyS10”, “Details”: “stock” } ], “cat1”: [ { “id”: 3, “Category_name”: “cat1”, “Name”: “iphone5s”, … Read more
Here if you have defined i<=user.length that means i<=5 since you array length is 5 but when you are indexing the array to print it can print between 0 to 4 indexes when it reaches index 5 there is no value in the array for index 5 hence it throws index out of bound error. … Read more
Just use data[i].wardid to retrieve the Ward ID from inside a simple for loop and compare that same ID with any value that which in turns, retrieve the Area ID value of that same object. In the following code snippet, I appended the corresponding Area IDs of the searched Ward ID to a new array … Read more
with open(‘foo.txt’, ‘w’) as f: for i, array in enumerate([Array_1, Array_2]): for s in array: print(f'”{s}”‘, i, file=f) Where ‘foo.txt’ is the path to your text file. 1 solved How to use python join the arrays and specify from which array?
the “array” variable is not well initialized. To capture the output of the commands you are executing, they should be sourrounded by $() With this change, the script works for me: array=$(grep “\bd=” $file | sed -r “s/(-)?[0-9]+(\.)?(-)?([0-9]*)?,(-)?[0-9]+(\.)?(-)?([0-9]*)?/{ & },\n/g” | grep -o “{.*},”) 0 solved Exporting SVG image to points using bash
The loop for(int i=0; i<5,i++;) is wrong. The condition i<5,i++ means i++ because the left operand of the comma operator i<5 doesn’t have side effect and simply ignored. i++ is evaluated to the value before the increment. In this case the value is 0, so it is considered as false and the loop body won’t … Read more
Try: a = [(‘aa’, ‘bb’, [‘cc’, ‘dd’]), (‘ee’, ‘ff’, [‘gg’, ‘ff’])] def flatten(tup): lst = [] for x in tup: if isinstance(x, list): lst += x else: lst.append(x) return tuple(lst) output = [flatten(t) for t in a] print(output) # [(‘aa’, ‘bb’, ‘cc’, ‘dd’), (‘ee’, ‘ff’, ‘gg’, ‘ff’)] As you pointed out, applying How to make … Read more
