3. Suppose you have an array of n random elements. You
are required to perform n different searches on the array. What is
best big-oh time for your entire task? Explain how to achieve that
time.
4. Suppose you are given two sorted integer arrays int[] A and
int[] B. Write a method that returns an array which contains only
the common elements (elements that are present in both A and B) of
these two sorted arrays. Indicate the big-Oh time of your
method.

Given a sorted (in ascending order) integer array nums of n elements and a target value, write a method to perform a binary search for a target value in nums. If target exists, then return its index, otherwise return -1. Analyze the running time, T(n). public int search(int[] nums, int target) { // YOUR CODE GOES HERE } // end search

I need help In the lecture you got acquainted with the median algorithm, which calculates the median of an unsorted array with n∈N elements in O (n). But the algorithm can actually do much more: it is not limited to finding only the median, but can generally find the ith element with 0≤i <n. Implement this generic version of the median algorithm by creating a class selector in the ads.set2.select package and implementing the following method: /** * Returns the...

1.) Complete the merge method below, which is the merge step of MergeSort. That is, it takes two sorted arrays as input and returns a new sorted array that contains all the elements from the two input arrays. Furthermore, it should keep all duplicated values, and it should run in O(n) time, where n is the size of the output array. public static int[] main(int[] a, int[] b) { }

Selection Sort is a common algorithm to sort the elements of an array. First, it scans the elements of the array to find the smallest value and places it at index 0, thus creating a sorted “subarray” of size 1 that contains the smallest value. Then it scans the remaining unsorted values for the new smallest value and places it at index 1, creating a sorted subarray of size 2 that contains the 2 smallest values. It continues in this...

Please answer by mathematical language: An array of n elements is almost sorted if and only if every element is at most k spots away from its actual location. Assuming that you can only perform pairwise comparisons, formally prove that any algorithm which can sort almost sorted arrays must have running time Ω(n log k), You may assume that n is a multiple of k.

(9) Complete the below Java method recursively, which takes in a String and returns if it's a palindrome. Remember a palindrome means a string that is the same reversed, like "deed", "racecar" or "tacocat". The empty string "" is also a palindrome. public boolean isPalindrome (String word) { (8) (a) (8 points) Implement merging two sorted arrays into one sorted ar- ray. These arrays are sorted in descending order. For example, (5, 4, 2). Return an array with all the...

Question 4 6 points You have to design an algorithm that verify if an array contains duplicate values. This algorithm simply returns true as soon as two identical values are found. To perform this task you must not change the order of the elements in the array (so you cannot sort it) or use an auxiliary array. Write the pseudo-code of this algorithm and give the Big-2 complexity in the worst case.

JAVA: Suppose you have the following array declaration and initialization: int [ ] values; values = new int[18]; Suppose there is a static method called sumAll that is sent an integer array. The sumAll method computes and returns the sum of all the integers in the array that it is sent (assuming the array is filled). Choose the best example of calling this method: Group of answer choices a) sumAll( values[0], values.length ) b) sumAll( values[0 .. 17]...

(b) Suppose you are designing a search aggregator, which for a given query fetches search results from two different search engines and presents an intersection of the two search results. Here is a simplified version of this problem: Given two sorted integer arrays of lengths m and n, return a new array with elements that are present in both input arrays. The input array may contain duplicates, but there should be no duplicates in the output array. For example, if...
