1. Implement a program in Java that, given an array of n integers, places all positive elements atthe end of the array without changing the order of positive and negative elements with anO(n) running time complexity.a. Example:b.Input: arr[] = {1,-1, 3, 2, -7,-5, 11, 6}c. Output: -1 - 7-51321162. Prove that your algorithm takes (0(n)) running time to compute this task. Formulate thesum equation for this proof.

Write an efficient algorithm (to the best of your knowledge) for the following problem, briefly describe why it is a correct algorithm, and analyze the time complexity. If you cannot find any polynomial-time algorithm, then give a backtracking algorithm. Problem: Repeated Number Input: An array A[1...3n] of positive integers. Output: If any number in the array appears at least n times, then print such a number. Otherwise, print 'none'. Example: Input: A = [1,3,3,3,1,1]. Here 3n = 6 and n =2. Output: 3. Note that here 1 would also be a valid output. You just need to print one if there are many options. Example: Input: A = [4,3,5,7,9,1]. Here 3n = 6 and n =2. Output: 'none'
Implement the following algorithms in Java: 3-WAY-QUICKSORT (slide 25). Explain in the report how yourimplementation operates.slide 25 : In 3-WAY-QUICKSORT, an array A[p..r] is divided in 3 parts −A[p..i] elements less than pivot −A[i+1..j-1] elements equal to pivot −A[j..r] elements greater than pivot. −Based on Dutch National Flag algorithm −Good when input has many duplicates
You're given an array arr. Apply the following algorithm to it: find intervals of consecutive prime numbers and consecutive non-prime numbers; replace each such interval with the sum of numbers in it; if the resulting array is different from the initial one, return to step 1, otherwise return the result. Input A non-empty integer array such that: -10000 ≤ arr[i] ≤ 10000 1 ≤ arr.length ≤ 1000 Output An integer array. Examples For arr = [1, 2, 3, 5, 6, 4, 2, 3] the result should be [21, 5]: [1, 2, 3, 5, 6, 4, 2, 3] --> [(1), (2 + 3 + 5), (6 + 4), (2 + 3)] --> [1, 10, 10, 5] [1, 10, 10, 5] --> [(1 + 10 + 10), (5)] --> [21, 5] For arr = [-3, 4, 5, 2, 0, -10] the result should be [1, 7, -10]: [-3, 4, 5, 2, 0, -10] --> [(-3 + 4), (5 + 2), (0 + -10)] --> [1, 7, -10] Solve it in C# please
in java ecplise . Implement a program that randomly generates 10 integers from -100 to 100,stores them in a 1D array, and finds their maximum value. Calculate theexecution time of finding a maximum. Repeat the test for 10,000 and10,000,000 numbers. Provide your results in the form of a table below andprovide a small summary. Implement a Java program that will populate a 5x5 matrix with randomlygenerated integers from 0 to 100.(1) print your matrix in a table form.(2) modify your code to multiply all even numbers by 10 and print the matrix.Your output of questions (1) and (2) should match the format of the followingsample outputs:
Given a sorted array arr[] of distinct integers. Sort the array into a wave-like array and return it In other words, arrange the elements into a sequence such that arr[1] >= arr[2] = arr[4] <= arr[5].. Example 1: Input: n = 5 arr[] {1,2,3,4,5} Output: 2 1 4 3 5 Explanation: Array elements after sorting it in wave form are 2 1 4 3 5.
