- Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information One statistic of interest to many researchers is the median of a set of data. The median is the value in the middle. (This is NOT the average, mind you.) Being in the middle, of course implies that the data are in order (sorted). If there are an odd number of data items, the middle is simple to find. If there are an even number of data items, you are supposed to take the average of the two middle values. You'll need to find the median of a set of data from a file. You don't know how many data are in the file, of course. You'll have to count the data, then read them in to sort, then find the median, and finally print it (the median) out. Do NOT use any more memory than is necessary!!arrow_forwardPython only** define the following function: 1. This function must add a task to a checklist, setting its initial value to False. It will accept two parameters: the checklist object to add to, and the task name to add. In addition to adding the task, it must return the (now modified) checklist object that it was given. There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.arrow_forwardPython question Application: Big-O Notation (Q8-11) For each of the time complexities in this segment give the tightest bound in terms of a simple polylogarithmic function using big-O notation. Note: use the ‘^’ symbol to indicate exponents, i.e., write O(n^2) for O(n2). Question 8 (Big-O Notation 1) T(n) = n2+ log n + n Question 9 (Big-O Notation 2) T(n) = n/3 + 4 log n + 2n log(n) Question 10 (Big-O Notation 3) T(n) = 7n5 + 2n Question 11 (Big-O Notation 4) T(n) = (n%5) + 12,000arrow_forward
- python only define the following function: This function must reset the value of every task in a checklist to False. It accept just one parameter: the checklist object to reset, and it must return the (now modified) checklist object that it was given. Define resetChecklist with 1 parameter Use def to define resetChecklist with 1 parameter Use a return statement Within the definition of resetChecklist with 1 parameter, use return _in at least one place. Use any kind of loop Within the definition of resetChecklist with 1 parameter, use any kind of loop in at least one place.arrow_forwardFunction Implementation with Data Abstraction in C Programming 1. Create a new file and SAVE as MATHV1.H Define and Implement the following functions: int sum(int x, int y); - returns the computed sum of two numbers x and y int diff(int x, int y); - returns the computed difference of two numbers x and y. Make sure that the larger number is deducted by the smaller number to avoid a negative answer long int prod(int x, int y); - returns the computed product of two number x and y float quot(int x, int y); - returns the computed quotient of two numbers x and y. Make sure that the larger number is always the numerator and divided by the smaller number to avoid division by zero error. int mod(int x, int y); - returns the computed remainder of two numbers x and y using the modulo operator %2. Create another new file and save as MYTOOLS.H void center(int row, char str[]); /*centers text across the screen -calculate here for the center col using the formula col=(80-strlen(str))/2; -then use…arrow_forwardErlang File -module(exam). -compile(export_all). -include_lib("eunit/include/eunit.hrl"). Part A Implement a function called min which takes a tuple of two numeric values and returns the lower value of the two.Implementation notes:• If needed, use Erlang function guards• Do NOT use the if or case structuresSample calls:> exam:min({3, 4}).3> exam:min({4, 3}).3arrow_forward
- C++arrow_forwardRevise the following Course class implementation in the following c++ code When adding a new student to the course, if the array capacity is exceeded, increase the array size by creating a new larger array and copying the contents of the current array to it. Implement the dropStudent function. Add a new function named clear() that removes all students from the course. Implement the destructor and copy constructor to perform a deep copy in the class. Write a test program that creates a course, adds three students, removes one, and displays the students in the course.arrow_forwardc programming Task 3: Complete armstrong_task3.c by implementing armstrong_recursive function. int armstrong_recursive (int arm); It performs same operation as in Task 1, however in a recursive manner. A number to be checked whether it is armstrong or not is given as an input and the function returns the summation of the digits. If the returned value is equal to the given input value then it is an armstrong number.arrow_forward
