Read MoreJavaScript Program for Check if an array is sorted and rotated
A sorted array is an array where all the elements are present in increasing order. We have given an array of size N and an array containing the distinct integers (which means every integer is present only one time). We have to check the array is sorted and rotated in a clockwise direction. Here we have to return ‘YES’ if the array is sorted and rotated otherwise, we have to return ‘NO’. Note − Here we are talking about the sorted and rotated means at least one rotation should be present. We cannot consider a sorted array as a sorted ...
Read MoreJavaScript Program for Ceiling in a sorted array
An array is a linear data structure that contains the objects and in sorted array elements are present in increasing order. We have given a sorted array and an integer x. We have to print the ceiling of the integer x from the given array. The ceiling of a sorted array with value x is the smallest element larger than or equal to x, while the floor is the largest member less than or equal to x. If the ceiling of the x does not exist in the array we have to print ‘ceiling of x does not exist in ...
Read MoreJavaScript Program to Check If a Singly Linked List is Palindrome
A singly linked list is a linear data structure that is stored in a non-contiguous way in the memory and each block is connected by holding the address of the next block also known as a node. A palindrome can be explained as a set of characters, digits, etc, and it reads the same from both the front and backside. We will be given a singly linked list and have to find whether the values stored at the nodes are equal from both the front and backside. Input 1 -> 2 -> 3 -> 3 -> 2 -> 1 ...
Read MoreHow To Modify This JavaScript Code To Grab An Image URL From A JSON File, And Display It In HTML?
This can be done by using the JavaScript method JSON.parse() to parse through the JSON file and extract the URL of the desired image.
