Program Plan Intro
Linear search:
- Linear search or sequential search is a process of searching for a particular element that is present in the array on by one till the last element until the search element is found.
- The search uses loop that iterates from the beginning till the last element to find the search element.
- The search continues for all the elements present in the array until the last element.
- The search of the target element is made after comparing with the each and every element that is present in the array.

- With an array of 20,000 elements, what is the maximum number of comparisons the binary search will perform?arrow_forwardDetailed answer please. I will Upvotearrow_forwardGiven an 8-element array: A = {x1, X2, X3, X4, X5, X6, 7, x8}, we would like to find its 3rd smallest element. It is known that x₁ and 8 are the two extreme elements: max and min, but we do not know which one is the max and which one is the min. It is also known that x4 and x5 are the two medians: left-median and right-median. What is the minimum number of comparisons you need to find the 3rd smallest element of the original array? Ans:arrow_forward
- How many times will the array {45, 47, 48, 51, 53, 54, 56, 57, 67, 70, 72, 73, 74, 79, 82, 85, 87, 89} need to be halved using binary search in order to find that element 30 is not in the array?arrow_forwardGiven a random array, please design an algorithm to find the median. First describe your algorithm, and then simulate your algorithm on the following array: {14, 2, 15, 1, 6, 30, 9, 7, 8, 11}.arrow_forwardConsider the following linear array: array=[-6,2,1,-5,-1,7,8] If you remove an element in index 2 and then insert an element in index 4, MINIMUM how many elements in total need to be shifted for the full operation? When an element in a particular index moves to its adjacent left or right index, it is counted as one shift. 7 8arrow_forward
- Assume an array has been ordered as (8, 14, 23, 45, 53, 67, 81, 85, 88, 94, 104, 111}. If we apply the binary search algorithm to this array to search element 104, how many iterations will be needed? (You need to show your work to receive full credit.)arrow_forwardHow many times will the array {70, 71, 72, 76, 80, 82, 83, 84, 87, 92, 95, 96, 102, 103, 107, 109, 111, 112, 113, 115, 116} need to be halved using binary search in order to find that element 112 is in in the list?arrow_forwardFor selection sort, how many comparisons would be needed to sort an array containing 100 elements if the original array elements were already sorted? What if the original array elements were sorted in reverse order? What if the original array elements were all identical?arrow_forward
- For insertion sort, how many comparisons would be needed to sort an array containing 100 elements if the original array elements were already sorted? What if the original array elements were sorted in reverse order? AV What if the original array elements were all identical?arrow_forwardBy calculating the percentage of non-zero elements in the matrix and deducting it from 1, you may determine the sparsity of a sparse matrix with Python code. which identifies the manually derived sparsity.arrow_forwardUse insertion sort to sort the following array (6, 2, 5,9,4, 2, 3, 7, 1, 8, 5}. Any observations here? Is insertion sort stable or not? Is insertion sort in-place or not?arrow_forward
