## Write random elements to div having class names from array using JavaScript

This is an example where I am going to show you how to write random elements to div having class names from array using JavaScript. Let’s consider we have multiple div tags on a web page and these div tags are created dynamically based on certain condition but you are not sure how many div tags will be created on the page.

## Segregate Positive followed by Negative Elements in an Array

Introduction This example will show you how to segregate positive followed by negative elements in an Array using Java programming language. The elements are integer values here. The function will put all positive numbers first, and then negative numbers and finally count the number of moves required to arrange all elements in the desired order.

## Minimum Moves to Equalize Array Elements

Introduction Here I will show you how to find out minimum moves to equalize array elements. I will check the equality of elements from two arrays. As a pre-condition both arrays must have equal number of elements, i.e., in other words both arrays must be of same length. I will read each element from both arrays one by one at a time and check how much difference are there between two elements at the same index of both arrays and add to the counter variable to keep track of the…

## Minimum moves to segregate even followed by odd elements in Array

Introduction This tutorial will find out minimum moves to segregate even followed by odd elements in Array using Java programming language. The function will put all even numbers first, and then odd numbers and finally count the number of moves required to arrange all elements in the desired order.

## Return array of products of all other numbers from a given array

Introduction This tutorial will show you how to return array of products of all other numbers from a given array. Let’s say you are given an array of non-zero integers. So you have to return an output array of products of all other numbers except the number itself.

## Finding Start and End Index of an element in a sorted Array using Kotlin

Finding start and end index of an element in a sorted array using Kotlin programming language will be shown here. The array may contain duplicate elements and we will see how to find a start and end index for an element in this array elements. We may design the algorithm for finding start and end index of an element in a sorted array in various ways but we need to consider also for the optimized solution. We can simply iterate through array elements and find the start and end index…

## Hackerrank Solution: 1D Array – Part 2 using Kotlin

This tutorial will show you Hackerrank 1D Array Part 2 using Kotlin. Let’s play a game on an array! You’re standing at index 0 of an n-element array named game. From some index i (where 0 <= i < n), you can perform one of the following moves: Move Backward: If cell i-1 exists and contains a 0, you can walk back to cell i-1. Move Forward: If cell i+1 contains a zero, you can walk to cell i+1. If cell i+leap contains a zero, you can jump to cell…

## HackerRank Solution: Subarray using Kotlin

This tutorial will show you how to solve HackerRank Subarray using Kotlin. A subarray of an n-element array is an array composed from a contiguous block of the original array’s elements. For example, if array=[1,2,3], then the subarrays are , , , [1,2], [2,3], and [1,2,3]. Something like [1,3] would not be a subarray as it’s not a contiguous subsection of the original array. Please go through first how to create Kotlin project in Eclipse

## Move Non-Zero Array Elements to Left using Java

This examples shows how to move all non-zero elements (if any) in an array to the left and all zero elements to the right in the array using Java. Your integer array may hold zero (0) and non-zero (1, 2, 4, etc.) elements. You have a requirement to have all non-zero elements first followed by 0 elements in the array. So this example helps you how to do it.
