Lab 16 Implementing bubble sort In this lab, you will implement the bubble sort algorithm. The bubble sort is so called because it compares adjacent items, "bubbling" the smaller one up toward the beginning of the array. By comparing all pairs of adjacent items starting at the end of the array, the smallest item is guaranteed to reach the beginning of the array at the end of the first pass. The second pass begins again at the end of the array, ultimately placing the second smallest item in the second position. During the second pass, there is no need to compare the first and second items, because the smallest element is guaranteed to be in the first position. Bubble sort takes at most n - 1 passes for an array of n items. During the first pass, n - 1 pairs need to be compared. During the second pass, n - 2 pairs need to be compared. During the ith pass, ni pairs need to be compared. During the last pass, n(n-1) or one pair needs to be compared. If, during any pass, no two adjacent items need to be interchanged, the array is in order and the sort can terminate. If it continues, no further interchanges will occur.

Best Partition You are given an array of positive numbers of size N and an integer K. You need to partition the array into K continuous segments. For each segment, the sum of its elements needs to be calculated. The segment with the minimum sum is called the bestSegment and the sum of the elements of the bestSegment is called the bestSum. For all possible combinations of partitions of the array when divided into K segments, their bestSum needs to be calculated and the one among them with maximum value needs to be returned. Input Specification: input1: an array of N positive numbers input2: an integer N denoting the length of the array input3: an integer K Output Specification: Return an integer denoting the maximum value of all possible bestSum. Example 1: input1: (1,2,3,4} input2: 4 input3: 2 Output: 4 Explanation: You can partition the given array into 2 continuous segments in the following manner- • 123 14- the sum of individual segments is (6,4) and the bestSum is 4 • 12134- the…
True or False. A simple variable, also called a scalar variable, is one that is unrelated to any other variable in the computer’s internal memory. The bubble sort algorithm gets its name from the fact that as the larger values drop to the bottom of the array, the smaller values rise, like bubbles, to the top. Programmers use arrays to temporarily store related data in the internal memory of the computer. Different variables in the same array may have different data types. The elements in an array can be used just like any other variables. When an array is sorted in ascending order, the first element contains the largest value and the last element contains the smallest value. When passing an array by reference in C++, you do not include the address-of operator before the formal parameter’s name in the function header. You distinguish one variable in a one-dimensional array from another variable in the same array using a unique integer,…
Median Function – In statistics, the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, the median is the average of the two middle values. Your program should start with two arrays of integers containing the following values: Even numbered array: 17 32 45 68 99 101 67 89 22 27 Odd numbered array: 17 32 45 68 99 101 67 89 22 Using a sort function of your choice, first sort the arrays. NOTE: you may use the Standard Template Library sort function or your own sort function. Then, write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. The same function should be called twice – once for the even array and once for the odd array. Your program should also have a printArray function that can be used to print the sorted array. (It…
Task - Median elements (C Langugage) Given an array of integer elements, the median is the value that separates the higher half from the lower half of the values. In other words, the median is the central element of a sorted array. Since multiple elements of an input array can be equal to the median, in this task you are asked to compute the number of elements equal to the median in an input array of size N, with N being an odd number. Requirements Name your program project4_median.c. Follow the format of the examples below. The program will read the value of N, then read in the values that compose the array. These values are not necessarily sorted. The program should include the following function. Do not modify the function prototype. int compute_median(int *a, int n); a represents the input array, n is the length of the array. The function returns the median of the values in a. This function should use pointer arithmetic– not subscripting – to visit array elements. In other…
Task 3: Statistics using arrays: by java programming With the spread of COVID 19, the HR department in a company has decided to conduct some statistics among the employees in order to determine the number of infections according to some conditions. For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no. You need to choose one service from each category (‘A’,’B’,’C’,’D’) a. A. Display the total number of employees that were infected b. B.…
ARRAY RANDOMIZER Create a program that shuffels all the elements present in an array. To shuffle an array, you need to do at least 500 random swaps of any elements in the array given below. Print the shuffled array in the output. {12, 54, 22, 100, -3, 5, 10, -33, 78, 90, 29, -45, 77, -9, 19, 21} Language: CPP
Search Benchmarks Design an application in pseudocode that has an array of at least 20 integers. It should call a module that uses the sequential search algorithm to locate one of the values. The module should keep a count of the number of comparisons it makes until it finds the value. Then the program should call another module that uses the binary search algorithm to locate the same value. It should also keep a count of the number of comparisons it makes. Display these values on the screen.
Select only the correct answers * right wrong An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier. When working with nested loops, the inner loop changes only after the outer loop is completely finished
1. initialise a variable named max and set its value equal to first item of array. 2. start a for loop to iterate through every element of marks array. 3. check if item> max. 4. if 4 is true: set max = item, else continue 5. after the loop will finish, max variable will have maximum marks
True or False For each statement below, indicate whether you think it is True or False If you have an array with no “holes”, the append function performs at O(1) Inserting an element at the front and shifting all elements performs significantly worse than appending an element at the end of the list For the insert function, if the array is empty, there are no comparison operations that need to be performed and you can immediately add the new element Binary search can be used on an unsorted array to significantly improve its performance from O(n) to O(1) Because the update algorithm depends on using linear search, its performance is O(1) in the worst case scenario True If you search for and delete an element in an unsorted array and then shift the rest of the elements to fill the hole, the worst case performance is O(n) If you search for and delete an element in an unsorted array and then move the last element to fill the hole, the worst case performance is O(n)
