In python, count the neighboring *'s of each individual element in this array: * * . . . . . . . . . * . . . then output an array where each element is replaced with the numbers of *'s above below and diagonal to them. The output should look like this: * * 1 0 0 3 3 2 0 0 1 * 1 0 0
You are given a bitonic sequence, the task is to find the bitonic point in it. A Bitonic Sequence is a sequence of numbers which is first strictly increasing then after a point strictly decreasing. A Bitonic point doesn’t exist if array is only decreasing or only increasing. (Input : arr[] = {-3, -2, 4, 6, 10, 8, 7, 1} Output: 10)
Write a python program to print the prime numbers existing in an array. For instance, if A = [4, 7, 12, 3, 9], the output should be 7, 3.

An input array consists of multiple integers. Write a sorting program to sort the content of thearray in place.Sample:Input: {4,2,0,3,4,0,4,1,2,1,3}Output: [0 0 1 1 2 2 3 3 4 4 4]
USE PYTHON 5.Write an algorithm that given a sequence of numbers, sorts, even numbers in ascending order, odd numbers in descending order and places all even numbers in the initial part of an array then odd numbers. Example: 2, 5, 1, 0, 4, 7, 9, 3, -2, 10, 20, 15 The answer is: -2, 0, 2, 4, 10, 20, 15, 9, 7, 5, 3, 1.
Java problem From the given array, create pairs of numbers from left to right, find the absolute value of the difference between each pair, find the minimum and maximum of the absolute values, and return it to a String array of size 1. Output format : {min_value : max_value} Sample input = {2,-1,4,7,2} Sample output={2:8}
Given an integer array nums, rotate the array to the right by k steps, where k is non-negative. Example 1: Input: nums = [1,2,3,4,5,6,7], k = 3Output: [5,6,7,1,2,3,4]Explanation:rotate 1 steps to the right: [7,1,2,3,4,5,6]rotate 2 steps to the right: [6,7,1,2,3,4,5]rotate 3 steps to the right: [5,6,7,1,2,3,4]Example 2: Input: nums = [-1,-100,3,99], k = 2Output: [3,99,-1,-100]Explanation: rotate 1 steps to the right: [99,-1,-100,3]rotate 2 steps to the right: [3,99,-1,-100] Constraints: 1 <= nums.length <= 105-231 <= nums[i] <= 231 - 10 <= k <= 105 Follow up: Try to come up with as many solutions as you can. There are at least three different ways to solve this problem.Could you do it in-place with O(1) extra space?
Check if Array Elements are Consecutive in Java. Given an array, we need to check if array contains consecutive elements. For example: Input: array[] = {5, 3, 4, 1, 2} Output: true As array contains consecutive elements from 1 to 5 Input: array[] = {47, 43, 45, 44, 46} Output: true As array contains consecutive elements from 43 to 47 Input: array[] = {6, 7, 5, 6} Output: false As array does not contain consecutive elements.
