Solve using JAVA only Given a square chess board of size N, solve the N queens problem. Print out the number of solutions for a given N. You do not need to print out or produce the actual solutions, only the number of correct solutions. Solve for N between 2 and 8. Try your program with 9 and 10, produce those results if it returns in a reasonable amount of time. The N queens problem is to find every configuration of N queens distributed on an NxN square chess board such that all queens are safe from attack by each other.

Write a program in java for the below given problem statement: Given 2 sorted arrays (in increasing order), find a path through the intersection that produces themaximum sum and return the maximum sum. That is, we can switch from one array to another array only atcommon elements. If no intersection element is present, we need to take the sum of all elements from thearray with greater sum.Sample Input:61 5 10 15 20 2552 4 5 9 15Sample Output :81Explanation :We start from array 2 and take sum till 5 (sum = 11). Then we'll switch to array at element 10 and take till15. So sum = 36. Now, no elements are left in array after 15, so we'll continue in array 1. Hence the sum is81.
write a java program that outputs a walk, trail, path, closed walk, circuit, and cycle of a given directed graph matrix. That matrix is to be hard coded as such... There are 4 vertices in this directed graph. We know that because there are 4 rows and 4 columns. If there is a 1 that means that the vertex on the left (you need to name them) has an arrow edge towards the vertex on the top. If there is a 2 that means there are two directed edges in the same direction going from the left vertex to the vertex on the top. If there is a 0 that means there are no edges from the vertex on the left to the top vertex. 1 2 2 1 2 1 2 1 2 2 1 2 1 1 1 0 - Make sure to program the matrix in to your code. - Output an example of each, make sure they are labeled. (6 outputs ) Example of a directed graph matrix below. The red numbers around the matrix are the vertices. If there is a 0 it means there is no edge from the vertex on the right to the vertex on the top.
Implement a program in python to solve the 8 Queens Problem using a genetic algorithm. The aim of the N-Queens Problem is to place N queens on an N x N board, in a way so that none of them can attack the other (means when any queen moves in directions vertical, horizontal and diagonal no other queen found in the path)
Please help. How to solve this on Java language by using only Dynamic Programming? Thank you. We are given a set A of integers. Check whether we can partition A into three subsets with equal sums. It is important to note that all elements should be included in the equally divided subsets; no element should be left out, and none of the elements should be repeated in the subsets.For example: A={4,7,6,2,10,7,10,2} has such a partition: {4,2,10}, {7,7,2},{6,10}Input: A set, A, of integersOutput: if we can partition A into three subsets with equal sums, print subsets otherwise present a suitable message.
Write a JAVA program to find the unique element which is present only once in the given array. All the remaining elements are repeated twice in the array. int []a = {2, 14, 6, 22, 2, 34, 22, 8, 6, 14, 8}; Use constant space and linear time.
Write a Java program to find continuous sub array of the given array whose sum is equal to a given number. For example, If {12, 5, 31, 9, 21, 8} is the given array and 45 is the given number, then you have to find continuous sub array in this array such that whose elements add up to 45. In this case, {5, 31, 9} is such sub array whose elements add up to 45.
Please help me Josephus Problem is a theoretical problem related to a certain counting-out game. On thiscase, people are standing in a circle waiting to be executed. After a specified number ofpeople are skipped, the next person is executed. The procedure is repeated with theremaining people, starting with the next person, going in the same direction and skippingthe same number of people, until one person remains, and is freed.Arrange the numbers 1 , 2, 3 , ... consecutively (say, clockwise) in a circle. Now removenumber 2 and proceed clockwise by removing every other number, among those thatremain, until one number is left. (a) Let denote the final number which remains. Find formula for .(b) If there are 70 people, what is the safe number (the number that remains)?
we have proven that the computational time complexity of mergesort is O(n * log2n). Perhaps the time complexity of mergesort can be improved further by separating the array into three parts instead of two. Start by implementing a method called merge3. This method should take three sorted arrays as inputs and return a sorted array consisting of all elements of the three input arrays. public static int[] merge3(int[] a, int[] b, int[] c) { return new int[] {-1}; } * must be done in this format and in java
FOR JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.
You are given a list of randomly arranged numbers, for example (11,7,18,5,17,13). The triple (11,7, 5) is called the "inversion triple" because (5<7<11) in terms of value, while the index of 5 in the list is greater than the index of 7, and the index of 7 is greater than 11. Therefore, we can find 2 inversions in such list as follows: (11,7,5), and (18,17,13). Your main task is to find the total number of inversions in any given list. a) Design a brute-force algorithm to return the number of possible inversions, and analyse the complexity of your solution b) Develop a python code to implement your brute-force algorithm. [The marks depend on the correctness of the code, indentation, comments, test-case] c) Design a more efficient algorithm to do the same task with less complexity, and analyse the complexity of your solution. [Important instruction to be followed: Create an arbitrary unsorted list of 8 characters and use it to provide full explanation of how your proposed…
Develop a brute-force algorithm that finds the longest common sequential elements of two given lists with the Java programming language. For example, the following two lists are given: S1 = [B,C,D,A,A,C,D] S2 = [A,C,D,B,A,C] Common lists are: [B,C], [C,D,A,C], [D,A,C], [A,A,C], [A,C], [C,D], … Note that although both lists have a common [C,D,A,C] (sub)list, both list items are skipped and the left-to-right order is intact. Apply the brute force algorithm. Explain Time Complexity?
