Select true or false for the statements below. Explain your answers if you like to receive partial credit 1) Which of the following is true about searching elements in an unordered array? a. With the data is unsorted, search is O(n) because if the element you are looking for is not there, you have to check every element in the array b. If you start at the end of the array and traverse to index 0, search improves to O(log n) because you only have to look at half of the array c. If you get lucky with checking the first element and find it immediately, then the worst case performance of search improves to O(n^2)

Select true or false for the statements below. Explain your answers if you like to receive partial credit2) Which of the following is true about searching elements in an ordered array?a. You cannot use binary search on an ordered array so the performance is O(n)b. If there are no holes in the array and the elements are all next to each other,then the performance for search improves to O(1)c. If you do a linear search on a sorted array, the performance improves toO(log n)
Below is how the arrays are represented ARRAY1[] = [1, 5, 6, 6, 9, 9, 9, 11, 11, 21] Here length of ARRAY1 is m. ARRAY2[] = [6, 6, 9, 11, 21, 21, 21] Here length of ARRAY2 is n. Array to be returned would be: ARRAY[] = [6, 9, 11, 21] ATTN : Further, please be reminded that you cannot use library functions to either sort and or perform the de-duplication operation. solve the problem in two ways In a separate implementation, code up a solution in such a way that your solution solves the problem with O(nlog(m)) time complexity 2 or O(mlog(n)) time complexity. Here log means to the base of 2. I’m sure you already know that the hint is to use Binary Search. In the form of sentences, as a comment in your code (at the bottom of your Solution2), you are required to suggest how can Solution2 be improved by leveraging the fact that both the arrays are already sorted. Suggest a solution so that your suggested solution can run linearly with O(m + n) time complexity. Your suggestion should be no…
True or False For each statement below, indicate whether you think it is True or False. If you like, you can provide a description of your answer. 5) Inserting elements into a sorted array is O(n) because you have to find the location to add the new element and then shift the remaining elements 6) If the sorted array gets too large, the performance of binary search becomes O(n) 7) For the delete algorithm, after you find the element to delete, you can make the algorithm run faster by replacing it with the last element in the array 8) If you used binary search to find the element to delete, the performance is still O(n) because you may have to shift all elements
1. You have an array of four integers that has been sorted from lowest to greatest value in the array. You also have a function that does a bubble sort in order to arrange things from lowest to greatest priority. If you call this method on your array, the function will perform at least one swap on your array. If false, why is it untrue?

c++ int primes={21,23,25,37,11,13,17.19,23,29,31,37,41,43,47,53,59,61,67,73,79,83,89,97} consider the above array of primes you have to search 53 in the array, also you have to check whether 53 is prime or not, also keep count of how many primes comes before 53.
Given the following array, what is the content of the array after Three passes of Insertion Sort? array: 44 12 50 3 40 23 Question 5 options: 3 12 44 50 40 23 12 44 50 3 40 23 12 3 23 40 44 50 12 3 44 50 40 23
Write code to locate a specific element in an array of n numbers that has been rotated an unknown number of times and is sorted. It is reasonable to believe that the array was initially arranged in ascending order.EXAMPLElnput:in{15, 16, 19, 20, 25, 1, 3, 4, 5, 7, 10, 14}Output: 8 (the index of 5 in the array)
Please Help me with This Question We are given two sorted arrays (all elements are in ascending order. We need to merge these two arrayssuch that the initial numbers (after complete sorting) are in the first array and the remaining numbers are inthe second array.
Why does this return an empty array and not 'G','H','I','J','K','B' x = ['A','B','C','D','E','F','G','H','I','J','K',]k = x[6:1]print(k)
True or False For each statement below, indicate whether you think it is True or False. If you like, you can provide a description of your answer. 1) If you use binary search on a sorted array, the performance at worst is O(log n) 2) For the insert algorithm, if you use binary search to find the location to insert the new element, it will improve the overall performance of the algorithm to O(log n) 3) For the update algorithm in a sorted array, all you have to do is use linear or binary search to find the element you want to change, and if you find it, you only need to change it to the new value 4) Binary search can be used on an unsorted array
