Hi, I have Java programming problem: Please solve using Java. Thanks. Best Regards. In the army, each soldier has an assigned rank. A soldier of rank X has to report to (any) soldier of rank X + 1. Many soldiers can report to the same superior. Write a function: class Solution { public int solution(int[] ranks); } that, given an array ranks consisting of soldiers' ranks, returns the number of soldiers who can report to some superior. Examples: 1. Given...
1. Please write a Divide-and-Conquer Java algorithm solving the following problem: Given an "almost sorted" array of distinct integers, and an integer x, return the index of x in the array. If the element x is not present in the array, return -1. "Almost sorted" means the following. Assume you had a sorted array A[0…N], and then split it into two pieces A[0…M] and A[M+1…N], and move the second piece upfront to get the following: A[M+1]…A[N]A[0]…A[M]. Thus, the "almost sorted"...
Parvati is given an array of integers. She is asked to return the sum of all the two-digit numbers in the array. Please help her to perform this task. Write a function: class Solution { public int solution (int[] A); } that, given an array A consisting of N integers, returns the sum of all two-digit numbers. For example, given A = [1, 1000, 80, -91], the function should return -11 (as the two-digit numbers are 80 and -91). Given...
Sorting Sort the following array using the quick sort algorithm: (4 Marks) a. 12 26 8 9 7 0 4 Pivot selection is defined to be the first element of each sub-list. Show the array before and after each quicksort round (when the array is partitioned after placing the pivot at its correct position). Also, clearly highlight the pivot in each partition b. Consider an unsorted array of integers of size n. Write a Java program to arrange the array...
Part I Short Answer (50 points) 1. Write a pseudocode declaration for a String array initialized with the following strings: “Einstein”, “Newton”, “Copernicus”, and “Kepler”. 2. Assume names in an Integer array with 20 elements. Write a pseudocode algorithm a For Loop that displays each element of the array. 3. Assume the arrays numberArray1 and numberArray2 each have 100 elements. Write a pseudocode algorithm that copies the values in numberArray1 to numberArray2 . 4. Write a pseudocode algorithm for a...
Hi, I have programming problem related to array, sorting, and. swap operation Thank you, Best Regards.. A non-empty array A consisting of N integers is given. You can perform a single swap operation in array A. This operation takes two indices I and J, such that 0 S13 J<N, and exchanges the values of A[i] and A[J]. The goal is to check whether array A can be sorted into non-decreasing order by performing at most one swap operation. For example,...
We are given an array A holding n integers, for some large n. The array is sorted, and the values in A range from -2147483648 to 2147483647, evenly distributed. Give Θ expressions for the following tasks: A. Running the insertion sort algorithm on the array A: B. Running the selection sort algorithm on the array A: C. Performing binary search for integer k which is not in A: D. Performing interpolation search for integer k not in A:
Write a function shuffle that takes an array of 20 integers and then shuffles the integers using the following algorithm. For each element X of the array, generate a random number N between 0 and 19, inclusive. swap X with the element that corresponds to N.
the programming language is in java Problem 2 You are given an array A with n distinct elements. Implement an (n log n)-time algorithm that creates an array B where all elements are in range from 0 to n - 1 and where the order of elements is the same as in A. That is, 0 has the same index in B as the smallest element in A, 1 has the same index in B as the second smallest element...
(7 pts) Problem 1 Consider this algorithm for partitioning an array a: 1. Create two new lesser and greater arrays. These will be used to store the elements of a that are sor > the pivot element, respectively. 2. Loop through all elements of a besides the pivot. If the element is the pivot, copy it into lesser. If the element is > the pivot, copy it into greater. 3. Create a new result array, of the same length as...
