Please solve the following algorithms problem: ( show all work solve asap ) Q550Create a divide and conquer algorithm for multiplication you do not need to analyze theruntime though, based on this equation.Let X be an integer with n digits. We divide X into:•XL: First [n/3] digits (approximately one-third of the digits)XR: Last n[n/3] digits (approximately two-thirds of the digits)Similarly, we break Y into:•Y: First [n/3] digitsYR: Last n [n/3] digitsRepresenting X and YXXL 102/3 + XRY Y 102/3 + YRMultiplying X and YTo multiply X and Y:XXY = (XL 102/3 + XR) × (YL · 102n/3+YR)

A magic square is an n by n matrix in which each of the integers 1, 2, 3...n appears exactly once and all column sums, row sums, and diagonal sums are equal. For example, the following is a 5 by 5 magic square in which all rows, columns and diagonals sum to 65. 17 24 1 8. 15 23 7 14 16 4 6. 13 20 22 10 12 19 21 3 11 18 25 9 The following is a procedure for constructing an n by n magic square for any ODD integer n. Place 1 in the middle of the top row. Then.m after integer k has been placed, move up one row and one column to the right to place the next integer k+1 unless one of the following occurs: If a move takes you above the top row in the jth column, move to the bottom of the jth column and place k+1 there. If the move takes you outside to the right of the square in the ith row place k+1 in the ith row in the left side. If the move takes you to an already filled square or if you move out of the square at the upper right hand corner place k+1 immediately below k. Write a C++ program…
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. Ridbit begins with an integer n. In one action, he can perform one of the accompanying tasks: partition n by one of its appropriate divisors, or take away 1 from n in case n is more prominent than 1. An appropriate divisor is a divisor of a number, barring itself. For instance, 1, 2, 4, 5, and 10 are appropriate divisors of 20, however 20 itself isn't. What is the base number of moves Ridbit is needed to make to decrease n to 1? Input The principal line contains a solitary integer t (1≤t≤1000) — the number of experiments. The main line of each experiment contains a solitary integer n (1≤n≤109). Output For each experiment, output the base number of moves needed to lessen n to 1.
Calculating the Minimum Sum Path in a Triangle (LeetCode Problem)Given a triangle array, return the minimum path sum from top to bottom. For each step, you may move toan adjacent number of the row below. More formally, if you are on index i on the current row, you maymove to either index i or index i + 1 on the next row. public static int minSumPathMemo(int[][] triangle)This method will calculate the minimum sum path in the triangle using the top down strategy. Note thismethod MUST BE recursive and you will need to create a recursive helper method. public static int minSumPathBottomUp(int[][] triangle)This method will calculate the minimum sum path in the triangle using the bottom up strategy. Note thismethod CANNOT be recursive and you should not create any additional helper functions. Extra Challenge: Could you do this using only O(n) extra space where n is the total number of rows in thetriangle? This is method signature class below: package dynamic; public class MinSumPath {…

9).An array of integers nums sorted in ascending order, find the startingand ending position of a given target value. If the target is not found in thearray, return [-1, -1]. For example:Input: nums = [5,7,7,8,8,8,10], target = 8Output: [3,5]Input: nums = [5,7,7,8,8,8,10], target = 11Output: [-1,-1]. Please weite your Code.
Using a Java program solve the following problem using arrays: Past A: Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program: Queen of Spades 5 of Clubs Queen of Hearts 4 of Diamonds Number of picks: 12 Sample run explanation: As you see in the above run, 12 picks are made to get the four cards from different suits. The other 8 picks (12-4-8) were from the…
