- Question 4 Full explain this question and text typing work only thanks You will create a Python notebook. You can create this file using your own local installation of Python and Jupyter or you may use Google CoLab. Write a computer program that implements the Find-Max-Crossing-Subarray and Find-Maximum-Subarray. Using the sample test data, verify that your implementation of the algorithm works and is correctCan you please show this problem step by step please.- Write a program that randomly generates a 20 x 20 two-dimensional array, board, of type int. An element board[i][j] is a peak (either a maximum or a minimum) if all its neighbors (there should be either 3, 5, or 8 neighbors for any cell) are less than board[i][j], or greater than board[i][j]. The program should output all elements in board, with their indices, which are peak. It should also output if a peak is a maximum or a minimum
- Solve both parts of the following question using R. Show the R code as well.Need help with this python question. You can't use break, str.endswith, list.index, keywords like: await, as, assert, class, except, lambda, and built in functions like: any, all, breakpoint, callable. ---------You also can't use Sorted---------- Create a recursive function def ab_equal(n, k, current): Print out all of the strings of a's and b's of length n so that the number of a's and b's are equal. For n = 2, there's ab and ba. For n = 3 there are no strings since they'd have to have 2 a's and 1 b, or 2 b's a 1 a so not equal. For n = 4, there will be 6 of these strings, and for n = 5, zero again. Hint: use k to track the difference between a's and b's. So for instance if your current is aaabb then k should be equal to either 1 or -1 (your choice depending). When you call the function, you should call it from your main or testing function with the length in the n parameter, 0 should be put into the k parameter, and then an empty string will be passed in for…Prove the following statement:
- 8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.I'm stuck on this question and I don't know how I should be approaching this. What should I do? Question: ------------------ Solving the N-Queens Problem Main Function Create a one-dimensional array of size n and seed it with -1 values. This represents an empty n x n chess board. Develop the problem with n=4, test the solution up to n=24. Note that the array index represents the row, and array value the column. Print Function Print the array where all -1 values are empty spots on the board and all values not equal to -1 represent the position of a queen. isSafePosition Test if a specific row/col position is safe for a queen relative to all previous rows (row-1). If placing a queen into this specific row/col position would be dangerous return false, else return true. Solve Use backtracking to provide a solution for the current board size. This is a recursive function which repeatedly tests different queen layouts until it ultimately finds a working solution. Your…USE JAVA The merge sort is a recursive algorithm that can be used to sort an array by first sorting smaller versions of an initial list of object. In this discussion, provide a simple of code sample of Merge sort and describe the benefits of using the merge sort. What are the key steps that must be taken to ensure an efficient sorting of objects? In your answer, specifically think of and give a real-life scenario where Merge sort may be used Merge sort may be a better fit than Quick and Radix sorts

Each digit is used exactly one time in each candidate replacement. X5XX + XXX3 = XX6XX Note There are 10! = 3,628,800 candidate permutations to check and 96 of the candidate permutations qualify as solutions. Of those 96 solutions, only 96 ÷ (2!×2!×2!×2!) = 6 are unique soultions.
