We are writing a JavaScript program to find the mth element after k right rotations of an array. Firstly, we will take the input for the array, m and k. Then, we will use a loop to perform the right rotations. In each iteration of the loop, we will move the last element of the array to the first position. We will continue this loop for k times to get the rotated array. Finally, we will return the mth element of the rotated array as the result. Approach The approach for finding the mth element after k right rotations of ... Read More

We will be describing the process of finding the median in a row-wise sorted matrix using JavaScript. First, we will traverse the matrix to gather all the elements into a single array. Then, we will sort the array to find the middle value, which will be our median. In case of an even number of elements, the median will be the average of the two middle values. Approach Given a row-wise sorted matrix, the median can be found by the following approach − Combine all rows into a single sorted array. Find the middle element(s) of the combined array, ...

We will be writing a program to find the maximum value possible by rotating the digits of a given number. We will be using a loop to break down the number into individual digits and rearrange them in a way that gives us the maximum value. The loop will continuously rotate the digits and keep track of the highest value obtained until all possible rotations have been evaluated. The maximum value obtained from this process will then be returned as the result. Approach To find the maximum possible value by rotating digits of a given number, follow these steps − ... Read More

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 write a program that utilizes the future continuous tense in order to find the maximum element of each row in a given matrix. This will involve looping through each row of the matrix and comparing the elements to find the maximum value. In order to implement this solution, we will use built-in functions such as Math.max() and loops to traverse the matrix and obtain the desired result. By the end of our program, we will have a solution that will be able to handle matrices of any size and provide the maximum value of each row in an ... Read More

We will be finding the lexicographically minimum string rotation in JavaScript. The method involves concatenating the original string with itself and then using the built-in 'sort' function to sort the concatenated string in ascending order. Finally, we will be returning the smallest substring of the sorted concatenated string which has the same length as the original string. This will be the lexicographically minimum string rotation. We will be implementing this logic by making use of string manipulation techniques and built-in functions available in JavaScript. The result of our implementation will be a string that represents the lexicographically minimum rotation of ... 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, as developers, are often asked to find if there is a subarray with 0 sum in an array. This can be done by using the concept of prefix sum. We will keep track of the sum of elements of the subarray seen so far and store it in a hash map. If the sum is seen before, it means that the subarray with this sum exists and has 0 sum. We will be continuously updating the hash map with the sum of elements seen so far. This way, we can determine if there is a subarray with 0 sum ... 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
