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…
TRUE OR FALSE You should not pass a one-dimensional array to a function.   Passing an array by reference is more efficient than passing it by value.   The quick sort algorithm provides a quick and easy way to sort the items stored in an array, as long as the number of items is relatively small—for example, fewer than 50.   The variables in an array may be stored in non-consecutive memory locations in the computer’s internal memory.   It takes longer for the computer to access the information stored in a disk file, than in an array in memory.
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.…
