Don't give me AI generated answer or plagiarised answer. If I see these things I'll give you multiple downvotes and will report immediately. Write a Java program that:Defines an integer array with a length of 15.Populates the array with unique integer numbers in random order.Implements three searching algorithms to find a specific target number:Linear SearchBinary Search (assuming the array is sorted)Jump Search (assuming the array is sorted)Tests these three searching methods by searching for a randomly chosen targetnumber in the array.Provides a brief explanation of the time complexity for each of the three searchingalgorithms in terms of n (the size of the array).Now, let's switch to a question related to data structures:Write a Python program that:Defines a linked list with at least 10 nodes, each containing an integer value.Implements three operations on the linked list:Insertion at the beginning of the listDeletion of a specific node by valueReverse the linked listTests these operations by inserting a new node, deleting a node with a specific value,and then reversing the linked list.Discusses the time complexity of each operation in terms of n (the number of nodesin the linked list).

In this question we have to write a Java Program for Search Algorithms on an Array and Python…

Implement the following method to sort the columns in a twodimensional array.

Given an array of length N and an integer x, you need to find all the indexes where x is present in the input array. Save all the indexes in an array (in increasing order). Do this recursively. Indexing in the array starts from 0.

Write a program that fills an integer array of size 1000 with random positive integers between 1 and 10.Assume that each element represents a different city and the integers stored in the array represent thenumber of golds in those cities. The program traverses over the array and collects the golds at each city,starting from a random position. When the program visits a certain city, all of the golds are collected,and the visited element of the array becomes 0 (no gold is left at that city.) The journey continues withthe rule given below. If the position at the nth step is denoted by pn, and the number of golds at the citypn is denoted by gn,??+1 = {| ((??−1 + ?? + ??) ???1000|, ????? 2 = 0| ((??−1 + ?? − ??) ???1000|, ????? 2 = 1.The program continues visiting cities until the last three visited city has no gold.The program, at each visit, should print out the following information:• The current city index (pn).• The previous city index (pn-1).• The number of golds at the current city…

In JAVA Recursive Array Search. Define and test a recursive method for a sequential search of an integer array. The method should return the index of the searchKey in the array, or return -1 if the searchKey is not found.
It is required that all rows in a 2-dimensional array have the same number of columns. To put it another way, we can only construct 2-D arrays of square or rectangular dimensions. True False in the programming language Java
URGENT 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}}.
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 {…
