A matrix can be defined as a 2D array that stores elements in it and mathematically it stores the numbers in it. A Lower triangular matrix is a squared matrix that has the same number of rows and columns and all the elements that are present above the main diagonal passing from the first cell (present at the top-left) towards the last cell (present at the bottom-right) are zero. We will implement a proper code with explanation and discussion over time and space complexity. Example Input 1: mat = [ [ 1, 0, 0, 0], [ 2, ... Read More

Rotating an array means moving the elements of each index (excluding one end ) to the following index for the right rotation and the previous index for the left rotation. For the right rotation zeroth index takes the value of the last index and vice-versa for the left rotation. Sort an array means that all the elements are in the proper increasing order. We will implement the proper code with an explanation and time, and space complexity discussion. Example Input: 5 6 9 10 2 3 3 4 Output: Yes Explanation: We can rotate the given array 4 times ...

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 More

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 ...

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 More

To check if a string can be formed from another string by at most X circular clockwise shifts, we can calculate the difference of ASCII value of the characters and then compare it with the X. Circular clockwise shifts for the string mean rotating the characters of the string to their next character in alphabetic order. In this article, we are given with a string, target and a number which represent the number of circular shifts to be made. Our task is to write a JavaScript program to check if the target can be formed from the string by at ... Read More

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 More

To check if a string can be obtained by rotating another string by 2 places, we have used Javascript substr() method. We will be understanding the code with an example and step wise explanation of the code. In this article we are having two strings: str1 and str2, where str1 is the given string and str2 is the rotated string. Our task is to check if the string (str2) can be obtained by rotating another string (str1) by 2 places. Example Input: str1 = TutorialsPoint str2 = torialsPointTu Output: true (with 2 left rotations) Input: ... Read More

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 More

jQuery is a popular JavaScript library that simplifies HTML DOM traversal, event handling, and AJAX interactions for rapid web development. It offers a wide range of built-in functions and methods that help developers to manipulate HTML elements, styles, and behaviors dynamically. In this article, we will see how to select all links inside a paragraph using jQuery. Selecting links inside a paragraph is a common requirement when we want to modify the links in a particular section of our website, such as changing styles, finding links, etc. How to select all links inside the paragraph? Selecting links inside the ... Read More
