We will be using a mathematical approach to find the maximum value of the sum of the product of the index and the value of the elements in the array. By rotating the array, we can maximize this sum by placing the maximum value of the array at the index with the maximum product. The algorithm we will be using involves finding the sum of the products of the index and values of the elements, then adding the difference between this sum and the product of the length of the array and the sum of the index values to this ...

We will be writing a JavaScript program to find the maximum number of zeros placed consecutively at the start and end of any rotation of a binary string. Our program will take a binary string as input and will return the maximum number of zeros that are placed at the start and end in any rotation of the given string. To solve this problem, we will be using string manipulation techniques to manipulate the input string and find the required output. In the next step, we will be rotating the input string and counting the number of zeros placed at ... Read More
We will be using the JavaScript array sort method and slicing technique to find the k maximum elements of an array in their original order. Firstly, we sort the array in descending order, and then slice it from the beginning to the kth index to obtain the k maximum elements. By preserving the original order of the elements, the significance and context of the data remains intact, making it easier for us to analyze and interpret the results. Approach The approach to find k maximum elements of an array in original order can be described as follows − Create ... Read More
We will be implementing a JavaScript program to find an element at a given index after a number of rotations. This program will require us to perform rotations on an array and then return the element present at the specified index. To accomplish this task, we will be using the modulo operator to calculate the new index after each rotation. The future continuous tense will be used throughout the explanation. In the program, we will be taking the input of the array, the number of rotations, and the index. We will then perform the rotations by using the modulo operator ... Read More
We will write a JavaScript program to find the sum of an array by using bitwise OR after splitting the given array into two halves after K circular shifts. Our program will perform the task by taking an array and an integer K as inputs. First, we will split the array into two halves after performing K circular shifts. Then, we will perform bitwise OR on both the halves to get a new array. Finally, we will find the sum of the new array obtained from the bitwise OR operation. Approach First, perform K circular shifts on the given ... Read More
In JavaScript, “” represents the empty string, and we can use the null keyword to initialize the string with a null value. If we don’t assign any value to any variable, it is undefined by default. Sometimes, we need to check if the string is empty, undefined, or null while working with the strings. For example, we are taking the details from the users via an HTML form, and users can add an empty string to the input field; we need to validate the input field and show the error message to the users. In this tutorial, we will learn ... Read More
A C++ string is a collection of characters forming words. It may contains letters, numbers and even special characters. The sentences of a string can be clubbed together in different ways to form different types of representations. The camel case of a string denotes the string in such a way that the following two properties are maintained − The words are joined together, there is no space character. Every word has the first letter stored in upper case. Thereby, the upper case letters in this form of representation can be used to segregate the different words. This type ... Read More
A string may be composed of several words. Every word in a C++ string may contain letters, numbers or special symbols. Strings are considered to be storage elements for these kind of characters. Each word is separated by a space character. Each word also forms a string of characters. Reverse of any string in C++ is the string follows the following points − It is formed by taking characters from the end towards the beginning. The length of the original string remains unchanged. The order of occurrence of characters in a string can be reversed easily by swapping ... Read More
A string is a sequence of characters, numbers, Alphanumeric characters and special characters. The length of a string is the number of characters that are present in it. A prime number is the number which is divisible by 1 and the number itself. In this artice, we are given a sample input string of length n. We are going to develop a code where the idea is to substitute the same character at any position p, such that the the characters at positions ranging from 1 to n/p should coincide. Some of the examples illustrating the problem statement ... Read More
Every string is formed by a sequence of characters arranged in an order. The string may be composed of letters, number or even special characters. An anagram of any input string, is the string with a random permutation of characters. This implies, that when the order of the characters is rearranged, an anagram of the string is obtained. The respective counts of the characters should also remain the same in anagrams. Two anagram strings have the following implications − Both of them contains the same set of characters. Both of them may have a different permutation of characters ... Read More
