4- Write a Scheme procedure that takes a list and returns the sum of the even numbers that are less than 8 in the list. For example, (sumeven '(1 2 6 48 5)) returns 12 and (sumeven ( 1 2 6 (45) 8 5) returns 12. Then, manually trace your procedure with one of the provided examples.

Write a statement, using pyhton language, that creates a two-dimensional list with 5 rows and 3 columns. Then write nested loops that get an integer value from the user for each element in the list.

How to write reporting function on this question This program implements the buying and selling of stocks. It starts by printing a welcome message Welcome to mystocks.com Then a main menu of choices for the user is output. Reporting, buying or selling? (0=quit, 1=report, 2=buy, 3=sell): The program ends with a goodbye message. Thank you for trading with mystocks.com Use doubly linked list of stock_t structures. stock_t structure looks like: #define MAX_TICKER_LENGTH 6 typedef struct stock_t {   char ticker[MAX_TICKER_LENGTH];   date_t date; // date bought   int numShares;   double pricePerShare; } stock_t; date_t structure looks like: typedef struct date_t {   int month, day, year; } date_t; Create the following files in a directory: date.h: contains the above date_t structure • stock.h and stock.c: contain the stock structure and any constants and stock function prototypes. Eg: a print stock function. • node.h, node.c: contain at least the node typdef and initNode function •…

python help, please show all steps and include comments Write a function largerLst() that takes a list of numbers (i.e., int or float values) as a parameter and returns a new list constructed out of it. The list returned has all the values in the parameter list that are larger than the element immediately to their right, that is, larger than their right neighbor. If the parameter list is empty or there are no values larger than their right neighbor, then the function returns an empty list. Note that the last element in the list will never be included in the list returned since it does not have a right neighbor. The function should not change the parameter list in any way. Note that a correct solution to this problem must use an indexed loop That is, one that makes a call to the range() function to generate indices into the list which are used to solve the problem (Review lecture notes 8-1). A solution that does not use an indexed loop will not be accepted. Note in particular that you…

Question: Create a function that takes a tuple and returns a dictionary which is a histogram for counting the number of occurrences of each number in the tuple.The main program should take the dictionary, transform the elements into a list, use sort () to order the list (in ascending order) and after that display the list. Please use a picture, commentary for a better understanding and your own code thank you  for the exemple, it's the picture

Modify the sample code to prompt the user for a name. Have theprogram search the existing list for the entered name. If thename is in the list, display the corresponding phone number;otherwise display this message,The name is not in the current phone directory. #include<iostream>#include<iomanip> using namespace std;const int MAXNAME = 30;const int MAXTEL = 15;struct Tele_typ{char name[MAXNAME];char phone_no[MAXTEL];Tele_typ* nextaddr;};void display(Tele_typ*);int main(){Tele_typ t1 = { " Cage, Mark", "(555) 898-2392" };Tele_typ t2 = { " Dolan, Nick", "(555) 682-3104" };Tele_typ t3 = { " Lennon, John", "(555) 718-4581" };Tele_typ* first; first = &t1;t1.nextaddr = &t2;t2.nextaddr = &t3;t3.nextaddr = NULL;display(first);return 0;}void display(Tele_typ * contents) // of type Tele_typ {while (contents != NULL){cout.setf(ios::left);cout.width(25); cout << '\n' << contents->name;cout.width(20); cout << contents->phone_no;contents =…

python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.

QUESTION 4 in phython language Write a program that creates a list of N elements (Hint: use append() function), swaps the first and the last element and prints the list on the screen. N should be a dynamic number entered by the user.  Sample output: How many numbers would you like to enter?: 5 Enter a number: 34 Enter a number: 67 Enter a number: 23 Enter a number: 90 Enter a number: 12 The list is: [12, 67,23, 90, 34]
