This kinda works. I can think of a couple of cases where something like this would break, like if the arrays were like {9,9,9} and {9,9,9}, result would be {9,9,8} instead of {1,9,9,8}. It’s a minor fix that is being left as an activity to the reader. public static void main(String []args){ int[] number1 = … Read more
By assuming that you have an array like arr[n]: You can define another array to keep differences like diff[n-1] and then you just need a loop like: for(i=0; i<n-1; i++) { diff[i] = abs(arr[i]-arr[i+1]); } Don’t forget to include <stdio.h> and <stdlib.h>. 0 solved Absolute difference between consecutive array elements
You have a question in the format “No A is within a class B”. The algorithm for such problem is bool wrong = false; while ( /* there is another A */ ) { if ( /* check if it is NOT within a class */ ) { wrong=true; break; } } if (wrong) { … Read more
Because all your data is in the same file, your going to need to take a slightly different approach. Instead of passing in the item to fill out, I would have the function return the list of read questions: public IEnumerable<QuestionUnit> ReadQuestionFile() Then, read in a loop until you reach the end of the file. … Read more
Yes, it can easily be done using recursion. The idea is to check if there is already a node in the tree under which the new node can be fallen. For example, if the new node is “1.1.2”, then we have to check if the node “1.1” exists in the tree. I wrote a very … Read more
You could first think about how many operations it would cost to get all values to the highest value in the list. In a second step you can think if there could be a better solution if you try to reach highest-value+1, highest-value+2, highest-value+3, highest-value+4 . solved This question is asked in a coding test. … Read more
from itertools import chain l = [[‘password’, ‘_rev’, ‘_id’, ‘username’], [‘password’, ‘_rev’, ‘_id’, ‘username’, ‘name’], [‘password’, ‘_rev’, ‘_id’, ‘username’],[‘password’, ‘_rev’, ‘_id’, ‘username’,’country’]] list(set(chain(*l))) Output – [‘username’, ‘_rev’, ‘_id’, ‘name’, ‘password’, ‘country’] solved merge list of nested list to a single list which has lakhs of data python [duplicate]
From inspection, I can see that your month array is missing the month of May, and therefore only has 11 elements in it. As a result, when you iterate over the 12 elements in the temperature array, you will get an array out of bounds exception during the final temperature, because there is no corresponding … Read more
Code: string myArray= “a, 0, 0, 0, 0, 0, 0, 0, 0”; int pushregister; cin >> pushregister; if (pushregister == a) { myArray = “a, 1, 0, 0, 0, 0, 0, 0, 0”; cout << myArray; } else { cout << “Wrong input” << endl; } return 0; 3 solved Using cin, if statement, and … Read more
let dt = { “cars” : [ { “id”: 0, “color”: “blue” }, { “id”: 3, “color”: “-” }, { “id”: 0, “color”: { “id”: 0, “color”: “yellow” } } ] }; dt.cars = dt.cars.map(it=> { it.color = typeof it.color == “string” ? it.color : it.color.color; return it; } ) console.log(dt); solved How to transform … Read more
You could use this recursive, pure JavaScript function: The snippet below applies this function to the example data you provided and returns the required result: function extract(data, select, curpath) { var result = {}; // Part of the path that has been traversed to get to data: curpath = curpath || ”; if (typeof data … Read more
You need to tell compiler the type of item, so instead of casting info array to [AnyObject] type cast it to [[String:Any]]. if let imagesArray = info as? [[String:Any]] { for item in imagesArray { if let image = item[UIImagePickerControllerOriginalImage] as? UIImage { //Access image instance } } } 6 solved Ambiguous use of subscript … Read more

This is the sample answer .When I checked your question,I saw that I need to create one person class with name,accountNo,amount,accType,Date.When we check two array List to subtract,we need to find same AccountNo in both array.So we need to use contains method and I override equal and hashCode.My Sample Person class is just like: package … Read more
You can combine the two examples, as such: Take the DynamicArrayOfInt class, and add the main method of the Fibonacci class. Insert a new statement at the beginning of the main method instantiating a DynamicArrayOfInt object, as such: DynamicArrayOfInt arr = new DynamicArrayOfInt(); Replace every instance of numbers[x] with arr.get(x), and instances of numbers[x] = … Read more
