Program Plan Intro
Binary search
- • Binary search is a smart search process that searches for the particular element that is present in the array from the middle towards the left or right until the search element is found.
- • The search continues in a narrow way that it searches for the quarter of the array until there are no values left in the array to search or compare.
- • The search of the target element is made in the smart way it eliminates a portion of array based on the given element as the array is sorted.

Find (array, x)// first sort the array// search for element x using binary searcharrow_forwardBubble sort is used to arrange an array in an ascending or descending order. If we are using this algorithm to sort an array in descending order, then what will be the order of values after complete execution of outer loop 3 times: 9, 1, 4, 5, 2, 8, 6, 11, 7, 0 *arrow_forwardWrite a permutation of 9 integers which is not in sorted order. Sort the integers using the sorting algorithms: Bubble Sort, Insertion Sort, Selection Sort and Quick Sort. Assume that the numbers are stored in an array. You should show the contents of the array after each iteration for all the algorithms.arrow_forward
- 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.arrow_forwardIn main() for now: do these - one at a time, each in it's own loop (we will make functions out of them later –Declare an array RandArray with 20 integers –Assign each of the 20 values with a random value from 0 to 99 Hint: Use rand()%100 For mimir: Do not call srand at the top of main. // normally: Call srand(time(0)) at the top of main –(you need #include<cstdlib>) –Write another loop that prints the array, with index values Important: If the output values do not match mimir, please add srand(17); // inside your main function - at the top code format: #include <iostream>using namespace std; #include <cstdlib> // required for rand() int main(){ srand(17); // define a constant ARRAYSIZE that is 20 // declare randArray // set the 20 elements in randArray to be a random number between 0 and 99 // hint: use rand()%100 // print the 20 values return 0;}arrow_forwardThe worst case of insertion sort happens when: a. None of them O b. The array is sorted in reversed order O. The array is sorted in ascending order O d. The array is randomly sortedarrow_forward
- Choose one option. We can use Binary Search Algorithm in : Option 1. Unsorted Array. Option 2. Sorted Array.arrow_forwardDouble Insertion Sort is a variation on Insertion Sort that works from the middle of the array out. At each iteration, some middle portion of the array is sorted. On the next iteration, take the two adjacent elements to the sorted portion of the array. If they are out of order with respect to each other, then swap them. Now, push the left element toward the right in the array so long as it is greater than the element to its right. And push the right element toward the left in the array so long as it is less than the element to its left. The algorithm begins by processing the middle two elements of the array if the array is even. If the array is odd, then skip processing the middle item and begin with processing the elements to its immediate left and right. Implement Double Insertion Sort, being careful to properly handle both when the array is odd and when it is even. Using java.arrow_forwardShow how the Selection Sort works on this list array to sort it in ascending order. 55 35 20 80 90 40 60 95 10 75arrow_forward
