Chapter 8, Problem 16RQE
Program Plan Intro
Linear search:
- Linear search or sequential search is the process of searching for a particular element that is present in the array one by one till the last element in the search element is found.
- The search uses a 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 it with each and every element that is present in the array.

- If an array is sorted in _________ order, the values are stored from lowest to highestarrow_forwardQ.No.1. In computer science, binary search, also known as half-interval search, is a search that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. Develop the pseudo code that takes any number from user and performs Binary Search.arrow_forwardBinary 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_forward

Sorting• Begin by filling an array with random numbers:import numpy as npnp.random.seed(1012)DATASIZE = 1000MAX_VALUE = 10000000data = np.random.randint(0, MAX_VALUE, size=DATASIZE)• Write a function that is passed a numpy array. The function should walkthrough the array element-by-element, comparing the current element tothe next element. Swap if the next is smaller than the current – sortingthese two elements.• Write a second function that calls the above function n times, where n isthe number of elements (size) of the array. Pass the same numpy arrayeach time. 2. Bubble Sort• The sort from part 1 can be improved. If the data passed to be sorted isalready sorted, it still performs all of the work, as if the array was notsorted.Make two improvements:• Change the first function (the one that does the comparisons), so that it returns aboolean that states whether the array is sorted.
