We will be finding the longest bitonic subsequence in each array using dynamic programming. A bitonic subsequence is a sequence which is first increasing, then decreasing. To find the longest bitonic subsequence, we will use a two-step approach. First, we will find the longest increasing subsequence in the given array, then we will find the longest decreasing subsequence in the reverse of the given array. Finally, we will add the lengths of both the subsequences and subtract 1 to exclude the common element in the middle. Approach A bitonic sequence is a sequence that first increases and then decreases. The ... Read More

We will use the formula for simple interest to calculate the interest for a given principal amount, rate of interest, and time period. Simple interest is calculated as the product of the principal amount, rate of interest, and time period. This formula makes it easy for us to find the interest amount without having to calculate the compound interest. In our JavaScript program, we will take input from the user for the principal amount, rate of interest, and time period, and then use the formula to calculate the simple interest. We will then display the result to the user. By ... Read More

We will find the perimeter of a triangle by adding the lengths of its three sides. To do this, we will first declare three variables to store the lengths of the sides and then use the addition operator to sum these values and store the result in a fourth variable. Finally, we will print out the value stored in the fourth variable to get the perimeter of the triangle. Approach Here is a JavaScript program to find the perimeter of a triangle − function trianglePerimeter(a, b, c) { return a + b + c; } Explanation ... Read More

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
