- Select true or false for the statements below. Explain your answers if you like to receive partial credit Select true or false for the statements below. Explain your answers if you like to receive partial credit Which of the following is true about searching elements in an unordered array? 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 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 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) Which of the following is true about searching elements in an ordered array? You cannot use binary search on an ordered array so the performance is O(n) If there are no holes in the array and the elements are all next to each other, then the performance for search improves to…What will be the problem with the following algorithm for finding an item in an unsorted array?

- The code below computes the intersection (the number of entries shared by two arrays). It is assumed that neither array contains any duplicates. It computes the intersection by sorting one array (array b) and then iterating over array a to see if each value is in b (through binary search). What is its duration? nt intersection(int[] a, int[] b) {mergesort(b);}int intersect = 0;for (int x : a) {if (binarySearch(b, x) >= 0) {intersect++;return intersect; }}6. Read in two integers n and m (n, m < 50). Read n integers in an array A. Read m integers in anarray B. Then do the following (write separate programs for each, only the reading part iscommon).a) Find if there are any two elements x, y in A and an element z in B, such that x + y = z.b) Copy in another array C all elements that are in both A and B (intersection).c) Copy in another array C all elements that are in either A and B (union).d) Copy in another array C all elements that are in A but not in B (difference).Do In c ProgramBelow you will find code blocks necessary to insert a value into an ordered array given a position (index) to insert.

Find the 100 (M) smallest elements using the following implementations. Note if your computer cannot handle 1 million elements, you may reduce the size. However, you are NOT allowed to reduce the size too small which results in an insignificant execution time difference among all the algorithms. 1. Use quick sort and then print the 100 smallest elements.
- In the "Common Array Algorithms" section, you learned how to find the position of an element in an array. Suppose you want to find the position of the second match. You could remove the first match and start over, but that would be wasteful. Instead, adapt the algorithm from that section so that it starts the search at a given position, not zero. Complete the following code.Suppose we code: theArray ={{1,2,3}, {4,5,6}, {7,8,9}}; What happens if we code System.out.println(theArray[3][3]); a) The value 9 is printed b) An error results because there is no such element as theArray[3][3] c) The entire array is printed d) None of these.C++ 1- Creating an array of 8 random integers /// 2- Copying the elements from the first array to another array that fulfills the following condition: The sum of the element to twice its position is less than the square of the difference between the element that follows it and the element that precedes it except for the first and last element They are copied automatically //// 3- Finds the largest even number in the first array and in what position it is found //// 4- Finds the two smallest odd numbers in the first array and in what position it is
