Searching: bool linear_search(const bool binary_search(const int arr[], int n, int value, int& comparisons); int arr[], int start, int end, int value, int& comparisons); The linear_search function is to perform linear search iteratively from the beginning of a sorted array. It returns true if the target value is found in the array, false otherwise. In addition, the function shall store the number of comparisons performed by the algorithm in comparisons parameter. Since the array is sorted, it is important for the search to stop searching when all elements smaller than the given value have been evaluated. The binary_search function is to perform binary search recursively. It returns true if the target value is found in the array, false otherwise. In addition, the function shall store the number of comparisons performed by the algorithm in comparisons parameter.

Linear search can be used on:a. Unsorted arrays.b. Sorted arrays.c. Integer arrays.d. Any of the above.
Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements: • Use a helper method for reading a positive integer using an input validation loop. • Use a helper method for printing a matrix. Your helper methods should be private and…

Binary Search in descending order We have learned and practiced the implementation of the binary search approach that works on an array in ascending order. Now let’s think about how to modify the above code to make it work on an array in descending order.
The following code computes the intersection (the number of elements in common) of twoarrays. It assumes that neither array has duplicates. It computes the intersection by sortingone array (array b) and then iterating through array a checking (via binary search) if eachvalue is in b. What is its runtime?int intersection(int[] a, int[] b) {mergesort(b);}int intersect = 0;for (int x : a) {if (binarySearch(b, x) >= 0) {intersect++;return intersect; }}

Searches – Directed Lab Work1. When an object does not occur in an array, a sequential search for it must examine the entirearray. If the array is sorted, you can improve the search by using the approach described inExercise 2. A jump search is an attempt to reduce the number of comparisons even further.Instead of examining the n objects in the array a sequentially, you look at the elements a[j],a[2j], a[3j], and so on, for some positive j < n. If the target t is less than one of these objects,you need to search only the portion of the array between the current object and the previousobject. For example, if t is less than a[3j] but is greater than a[2j], you search the elementsa[2j + 1], a[2j + 2], . . ., a[3j - 1] by using the method in Exercise 2 on the textbook’s page544. The implementation should take care of the case when t > a[k × j], but (k + 1) × j > n.Devise an algorithm for performing a jump search.Then, using⌈√n⌉as the value of j, implement the jump search.

Following is the function for interpolation search. This searching algorithm estimates the position (index) of a key in array based on the elements in the first position and last position in the array, and the length of array. The array must be sorted in ascending order. Suppose array A contains the following 15 elements: A = [1, 3, 3, 10, 17, 22, 22, 22, 24, 25, 26, 27, 27, 28, 28] At first iteration, at which position (index) the element of 24 is estimated in array A? In which part of array (starting index and ending index) the searching should continue? How many iterations the searching are performed until the element of 24 is found? int InterpolationSearch(int x[], int key, int n) { int mid, min = 0, max = n-1; while(x[min] < key && x[max] > key) { mid = min + ((key-x[min])*(max-min)) / (x[max]-x[min]); if(x[mid] < key) min = mid + 1; else if(x[mid] > key) max = mid - 1; else return mid; } if…
C++ Write a ternarySearch function. A ternary search is similar to a binary search, but it divides an array into three sections instead of two - find the two points that divide the array into three (almost) equal sections, and then use these points to decide where to search for the key.
(Bucket Sort) A bucket sort begins with a one-dimensional array of positive integers to besorted, and a two-dimensional array of integers with rows subscripted from 0 to 9 and columns subscripted from 0 to n – 1, where n is the number of values in the array to be sorted. Each row of thetwo-dimensional array is referred to as a bucket. Write a function bucketSort that takes an integerarray and the array size as arguments.The algorithm is as follows:a) Loop through the one-dimensional array and place each of its values in a row of thebucket array based on its ones digit. For example, 97 is placed in row 7, 3 is placed inrow 3 and 100 is placed in row 0.b) Loop through the bucket array and copy the values back to the original array. The neworder of the above values in the one-dimensional array is 100, 3 and 97.c) Repeat this process for each subsequent digit position (tens, hundreds, thousands, andso on) and stop when the leftmost digit of the largest number has been processed
