3. Sort the array A= [10, 15, 11, 12, 6, 28, 19] by using the operation (insertion and deletion) of Heapsort.
A Queen on a chessboard can attack any piece in the same column, row or diagonal. The N-Queens problem is to place n queens on an x n chessboard such that no two queens threaten each other. a) Implement a one-dimensional integer array of Queen positions for an 8x8 board where indices represent rows and the values represent columns. For example, a "safe" solution would be (3,6,2, 7, 1, 4, 0,5} b) Implement a print function to display the board (see output example) c) Implement an isSafe function that: 1) Returns false if multiple queens share a column 2) Returns false if multiple queens share a diagonal 3) Returns true if all queens are safe d) Program should display if the Queens are safe or not safe. Example Output Testing: 1 4 2 3 5 7 60 Queens are not safe!
Why is it giving me an error and what do I have to change? PYTHON # Problem 2# Implement a hashtable using an array. Your implementation should include public methods for insertion, deletion, and# search, as well as helper methods for resizing. The hash table is resized when the max chain length becomes greater# than 3 during insertion of a new item. You will be using linear chaining technique for collision resolution. Assume# the key to be an integer and use the hash function h(k) = k mod m where m is the size of the hashtable. You can use# python list methods in your implementation of the chain or you can also use your linked list implementation from# coding assignment 2, problem 1. You can make necessary changes to  __hashtable initialization in the __init__ method# if you are using your linked list implementation. The provided code uses python lists for the __hashtable variable. class HashTableChain:    def __init__(self, size=10):        # Initialize the hashtable with the given…
