JavaScript Program to Check if it is possible to make array increasing or decreasing by rotating the array
Rotation of the array means to assume the array as a circular array and rotate the elements of the array to either their left or right direction by one index at each rotation and the element at one end may take the value present at another end. An Increasing array means that each element will be greater than or equal to its previous element and decreasing array means each element will be less than or equal to the previous element. In this problem, we are given an array and we can rotate the array in either the left or the ...
Read MoreJavaScript Program to Check if all rows of a matrix are circular rotations of each other
Matrix is a kind of 2-D array in which there is an array of fixed arrays that defines the rows and for each index of this array there are fixed length arrays present and the length of these arrays defines the number of columns present in the matrix. We can store any kind of data type in these cells provided by the matrix. We will be provided with a matrix and each row contains some integers and we have to check if each row is the rotation of one another or not. Rotation of each other means by some number ...
Read MoreJavaScript Program to Check if all array elements can be converted to pronic numbers by rotating digits
Pronic numbers are also known as rectangular numbers, the pronic numbers are numbers that are multiples of two consecutive numbers. We will be given an array of integers and we can rotate the digits in any direction for a certain number of times to get all combinations. For any combination produced by rotating the digit if each array element can be converted into the pronic number then we will print true otherwise false. Pronic Numbers First, let us discuss pronic numbers: pronic numbers are the numbers that are the product of two consecutive numbers. Mathematically saying, if we have integer ...
Read MoreJavaScript Program for Rotate Doubly linked list by N nodes
A doubly linked list is a linear data structure where each node stores the address of the next and previous node. We have given a doubly linked list and we have to rotate the doubly linked list by N nodes and print it. Here N is the positive number and less than or equal to the count of the nodes present in the linked list. We are not given the specific side to rotate the doubly linked list. So we will rotate the doubly linked list in both ways. Rotating Doubly Linked List to Counter Clockwise We have to rotate ...
Read MoreJavaScript Program to Check if a string can be obtained by rotating another string d places
Rotating a string means moving the characters of the string to their left or right side by one index and one end may contain the value stored at the other end. We will be given two strings and we have to rotate the second string either in the left or the right direction by given number (d) times and check if both strings are equal or not. We will write proper code with comments, explanations, and detailed discussions on the time and space complexity of the program. Examples If we have the given string ‘abcdef’ and the other string is ...
Read MoreJavaScript Program For Reversing A Linked List In Groups Of Given Size
A linked list is a linear data structure that consists of interconnected nodes. Reversing a linked list means changing the order of all its elements. Reversing a linked list in groups of a given size means, we are given a number and we will reverse the first given number of elements, and then for the next set we will reverse the elements. We will see the proper code with implementation. Examples Given linked list: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> null Given number: 3 Output: 3 -> 2 -> ...
Read MoreJavaScript Program for Reversal algorithm for right rotation of an array
Right rotation of an array means to rotate the elements of the array to their right side by a given number of times and for the number which are present at the edge they will move to the first index in their right rotation by assuming an array in a cycle form. We will implement a proper code to implement the algorithm with an explanation. Example Let us assume we have given array as [1, 2, 3, 4, 5, 6, 7, 8, 9] The number of right rotations of the array is 3 Output: 7 8 9 1 2 ...
Read MoreJavaScript Program for Reversal algorithm for array rotation
An array is a linear data structure used to store the different types of objects and we are given an array of size n and an integer k (where k is the number by which we will rotate an array). We will rotate the array by k elements and then return the rotated array. Rotation means we have to traverse the array from the given kth element and shift all the integers by one and we have to shift each element by 1 till the kth element came to position ‘0’ or we can say at index number ‘0’. Note ...
Read MoreJavaScript Program for Removing Duplicates From An Unsorted Linked List
The linked list is a linear data structure that consists of nodes, and each node is stored in memory in a non-contiguous manner. Nodes are connected by storing the address of the next node. We are given a linked list that will contain some integers in a random manner and not in a sorted manner. The task is to find the elements of the linked list which are repeated and we have to remove the duplicated ones. We will see the proper code and explanation. In this problem, we will keep the first copy of the elements of the ...
Read MoreJavascript Program for Range Queries for Frequencies of array elements
We are given an array that will contain integers and another array will be given that will contain the queries and each query represents the range that we are given by the leftmost and the rightmost index in the array and an element. For that range or the subarray, we have to find the frequency of the given element present in that range. The frequency of the elements means that we have to tell for each integer present in that range how many times it occurs. For example − If, the given array is: [5, 2, 5, 3, 1, 5, ...
